It is NOT scenery or AFCAD, I have not installed any ;)To anyone else getting the dreaded out of memory error message but can not explain it, Do you have Flight Deck Companion V 3.0 or V 3.1 installed? See this post...Dave,First off, I absolutely love the program and I am a LONG time user, all the way back to S-Combo LOL. Thanks for the V 3.1 update and Happy Holidays to you.Unfortunately however, I think I have a problem. Please allow me to give you a little background. I have been experiencing Out of Memory error messages for months now with two different systems and multiple h/w configurations. I can not remember the first time it happened but I think it is about the time of the LVL-D release. Now I am trying to think if it was around the time of the V 3.0 upgrade? I really only get it on long hauls and usually on approach or just after touchdown. I try to use the report landing runway feature but it usually does not report. I am wondering if that is looping and causing the issue. I get it with the PSS, LVL-D and PMDG 744. Like a lot of other users I had a tremendous amount of add-ons installed from Aircraft to utilities to sceneries etc... As such it was very difficult to ever track down what add-on caused the errors. I tried everything, ran memtest, ran heavyload, switched ram, video cards, motherboards, video cards sound cards, scanned for landclass, duplicate Afcad, removed sceneries but nothing would resolve the issue.For the past few weeks I have been on an absolute mission. I have formatted my system and started from scratch. With over 40 gigs in my FS directory this was no easy task. I first installed FSUIPC V 3.51 since upgrading to 3.52, then ActiveCamera. I flew like that with default aircraft for a few days no issues. I then installed the PMDG 737-NG and then the PMDG 744. I flew for a few days (straight without reboot) doing at least 5 or 6 long haul flights, no issues. I then installed the LVL-D, same procedure, multiple long hauls with no reboots and no issues, I then added the PSS 777 and did the same thing, flew for a few days without rebooting doing multiple long hauls. No issues.When I was confident it was not an aircraft issue itself I then installed ASV. Same thing, flew for a few days with all three planes and no issues. Next to be installed was FSPassengers. Did multiple flights with all 3 planes and FSP and again, no issues. Today I installed FDC, and perhaps it is the checklist or performance files I am using but they have all been updated and saved per FDC V 3.0 instructions but on my first flight with FDC installed I got an Out of Memory error almost imeediately after touchdown. This is the EXACT same behavior I was getting prior to formatting everything and starting from scratch. I can not say definitively it is FDC but I have been extremely methodical about my testing procedures and environment. There is absolutely NO add-on scenery or AFCAD files installed. The install order and problem replication path was as follows:1. Format completely2. Install XP and all patches including SP23. Install Vanilla FS (Test for days, no errors)4. Install FS Patch (Test for days, no issues)5. Install FSUIPC, FSBuild and ActiveCamera (test, no issues)6. Install PMDG planes (test no issues)7. Install LVL-D (test no issues)8. Install PSS (test no issues)9. Install ASV (test no issues)10. Install FDC (crash with out of memory error message on first flight...Just curious if anyone else seeing the issue had the same common factor= FDC...Disclaimer...Please do not view this as an attempt to bash FDC, I think it is one of the greatest programs ever, just trying to confirm a theoryLiquid CooledAMD 4000 San Diego2 Gigs Kingston Corsair XMS CL2Dual 7800 GTX 24 inch widescreen dual 19 inch LCDRaid-0

Just a quick update.I did the EXACT same flight as the one that CTD last night. I had even saved the wxr through ASV so I used the exact same wxr. Loaded up FsPassengers, everything was identical to the previous flight minus FDC. Will six hours 2 minutes later and I am on the ground at EGCC. No issues at all. I bet if I do the same flight with FDC again it will crash. just an update but it is definitely looking like FDC in my case, nothing to do with any of the add-on planes at all...-PaulLiquid CooledAMD 4000 San Diego2 Gigs Kingston Corsair XMS CL2Dual 7800 GTX 24 inch widescreen dual 19 inch LCDRaid-0
