Normally, drive "B" is assigned (reserved) for a second floppy drive.

 

Your Windows disk activity looks normal to me.

 

Are you getting logged errors in Windows Event Viewer saying ASN is causing a problem?

 

You have an application running called WarpAir.

What is it?

This is what my ASN activity (no problems) looks like (my hard drive drive F):

HI

 

I use drive B for FSX, cause no chance of floppy drives coming back to fashion

 

With FSX running most of the time as_svr is biggest disk user on FSX drive as you can see from my pics above.

 

FSX drive  gets too busy with FSX alone, any folder reaching top of demand going to join it their can only make it worse.

 

Looks like both mine and your pics are showing as_svr on top of demand on FSX drive to make a bad situation worse.

 

Normally my FSX drive is fairly quiet during cruise, with ASN there is constant activity on the drive delaying texture load and causing stutters.

 

I have moved form ASN till hotfix that hopefully allows user to set location of this very busy as_svr folder

 

From resource monitor the only resource that hits the roof constantly is disk , FSX is a very disk hungry app, and as such addons adding to that disk  demand, would be better to provide user option to locate the new traffic on a third drive, not OS or FSX drives cause they re too busy already as result of FSX alone. 

 

Try running with AS2012 and ASN and compare the signal on resource monitor waveform for FSX drive, its a constant saw tooth wave form as result of as_svr. This saw tooth wave form is not there with As2012 and FSX drive mostly flat during flat unless periods of heavy texture load. THis waveform is also visible from your pic above. FSX texture load waveform is more square waveform.

 

AS2012 is looking great with rex4, will sit there for now. AS2102 adds no extra heavy disk demand to FSX drive, but it does OS drive. Really, location of HOT folders need to be optional. most simmers spare drives that would be perfect for HOT addon folders.

Why do I not have problems like you report?

 

Even if files on another hard drive .. the same OS must use it ... the same usage .. just another location?

"Why do I not have problems like you report?"

 

Really AVSIM  should be renamed "Works for Me So Should Work For You"

 

Without much debate I end with this.

 

Neither myself nor my system or other HIFI users are making same complaint about AS2012. All you need do search ASN freeze in Google. In the past Had issues like this with REX weather and dumped it for AS2012, now ASN has the same resource balancing Bug leading to freezes in FSX.

 

 

 You asked for my disk monitor pics, so there they are to tell the story.

 

I suggest as_svr folder is the cause of my freezes, and moving it out of FSX drive  is reasonable fix.

I see your point regards OS drive still needs to access everything so that cant be helped, FSX drive can for most simmers who have spare drives. And issue here is about as_svr starving FSX drive of bandwidth.

 

 

 HIFI have said, working on fix, I got As2012 doing just fine with REX4 for now.

Hi!

 

For those who has had 8-minutes freeze, have you resolved it? I can't get rid of the freezes. Anyone with solutions?

I have determined (with a 90% confidence level)  that these 8 minute freezes are caused by the FSX default GPS.     I don't know why this is so but if you are using the GPS-500, and keep it on the screen while in flight, either don't use it or use it sparingly.   Perhaps a 3rd party GPS would not cause the problem.   A search for more information of this issue found that this specific problem occurred with FS9, also.

 

I have found no connection between these freezes and ASN.

}

I had this problem and here is what I did that seemed to fix it.

 

1. Uninstalled X Gauge - I'm not at all sure this had anything to do with the problem but it was the last change I had made before I had the problem so I just uninstalled it

2. Updated fsuipc to the most current version 4.9.2.8

 

Repeated the flight that I had the freeze problem with and there was no reoccurrence.

I've had these freezes for a couple of years. I had a new machine built 6 months ago for FSX only, and I'm still getting them. They occur while flying online with VATSIM, using FSinn and also when I'm not flying online. The freezes occurred before I ever had any Active Sky or PMDG products. I've deleted all scenery addon programs such as UTX, and have disabled all auto updates on other installed programs not related to FSX. The only other scenery I have are some freeware airport updates by Ray Smith and others from FlightSim.com. The settings in FSX are not unusually high, and I set all traffic to zero. I also eliminated all downloaded AI from my addon scenery file. VAS usage is always 3.2 or less and frame rates are good. They happen with or without an FSUIPC.dll installed, I've tried both ways. I always see a bright flash on the monitor just before the freeze. I have the latest NVIDIA drivers available. Does any of this sound familiar? Thanks.

Anybody fixed this yet? I only got the problem when I switched over from trial, to fully registered. (I reinstalled it when I bought it) 

I am reasonably sure the 8 minute hang is due to a windows kernal timeout for a failed IO operation; this is a documented 'feature' of windows BTW.  I thought I had this problem solved when I installed the latest version of the intel RST drivers; things had gone well for days until I took a screen shot about 45 min into a flight and then wham...8 minute hang.  I don't think it was a pure coincidence but I can't prove it.  BTW, I do run FSX from a dedicated SSD and my OS resides on a different SSD.  I wonder if HD users are also experiencing this.

Could you please direct to the relevant windows documentation?

 

It does happen in HD. In fact, it seems that is happening to a very wide range of hardware, so most probably It is connected to os/software issues.

Could you please direct to the relevant windows documentation?

 

This is what I referred to:

http://blogs.msdn.com/b/san/archive/2011/08/15/the-windows-disk-timeout-value-understanding-why-this-should-be-set-to-a-small-value.aspx

I've tried all of the fixes mentioned in this thread to no avail, though I don't use the affinity mask tweak since it causes hard stutters with my setup.  IMO this is a deep, nasty bug related to device drivers, hardware firmware and windows OS, which unfortunately ASN happens to trigger.  I've had the freeze occur anywhere from a few minutes to 2+ hours into a flight. 

It seems that you've got something there!

 

I am freeze-free for some time now, using the affinity mask (core0 left for OS and accompanying apps) and unlimited frames.

To my experience the 8min freeze is not directly related with ASN, as I have seen it (many times) without ASN in use (I have seen it many times with AS2012 in use). As you mention, ASN must be one of many things that can trigger it.

 

If someone knows what he is doing (and currently experiencing the freezes), he could modify the registry setting (e.g. to 30sec) and see if the freezes go down to 4min.

I also read in the article you provided, that windows should report in Event Viewer the timeouts. I was never able to find any record in EventViewer of these freezes.

 

Would you know where in EventViewer should we look for them?

I used regedit to set my disk timeout from 60 to 15 seconds.  So far my computer is happy with that change, e.g. my SSDs, HDs and optical drives are still functional.  I've yet to have an ASN inspired freeze up; I'll report my findings if one so occurs.  I don't see much comfort in this, unless you count trading a 2 minute wait for a 8 minute wait comforting.  I want it to be truly fixed.  My somewhat educated guess is that an IO completion interrupt is being lost/ignored somehow; perhaps it's the result of a "race condition" (that screen shot situation I mentioned comes to mind here).  I've yet to deep dive into any logs, next time one occurs I will.

Fully understand that this not a cure, but it will be proof that this is indeed the mechanism that gets triggered.

Your analysis is the first I come across that gives a logical explanation on this issue; the "race condition" assumption also makes sense.

 

If it is proved that the underlying mechanism is the one you describe, then I hope that experts (quite a few in this hobby) can "immune" addons and apps against it.

 

 

PS:

I have kept some logs from WhatIsHang during 8min freezes. The following was repeated in all cases:

 

Execute Address:

773E70F4 ntdll.dll!KillFastSystemCallRet

 

Call Stack:

Hope this can help more knowledgeable guys.
