bfr Posted May 22, 2023 Posted May 22, 2023 (edited) I have been having fairly regular crashes in multi-threaded SP ever since the last OB update (2.8.5.40170). Not in particularly taxing missions, just flying around. Zip from the last crash attached. I think any mods have been removed (did have the Blackhawk and F-104 unofficial mods installed) but I am still running with export entries for Tacview & DCS UFC for now. I have tried rolling back DCS to the prior OB version and it seemed better (would like to clock more time up to be certain about that). Any ideas/suggestions? dcs.log-20230521-211826.zip Edited May 22, 2023 by bfr Clarify using the MT exe

Whilst 2048MB sounds small (i'd just left page file settings as system managed), isn't resizing it to the equivalent of 100% of RAM a tad excessive? The recommended sizing in the Virtual Memory dialog for Windows seems to suggest a smidgen over 4GB (4964MB). EDIT: Also i'm not seeing anything in the log that its run out of memory anyway? EDIT2: Having had a bit of a dig and the recommendations I can find being min = 1/8th of RAM and max = 1.5x RAM then if I was going to set those values manually then they should be 4GB and 48GB respectively? I guess you could go 48GB across the board for min and max but why permanently give over ~5% of an SSD when the page file will hardly get touched most of the time? Still had a headscratcher though why current allocation when Windows manages it is 2GB (I realise now its probably dynamic but its still a curious starting point) when Microsoft's own recommendation is double that.

Perhaps a DCSism. Most people suggest 32 GB regardless of what physical memory the rig has. I have 128 GB RAM and still have static of 32. I do not have any crashes. I also did not see memory errors in the log. The pagefile suggestion is free and worth a shot IMO either way. In the initial days of Windows servers, it was suggested to do pagefile 3x to be able to capture the memory dump.

Yeah, I hear you regarding it being a hail-mary and i'll maybe have a tinker later just to see. I'm just a bit wary of stuff in those areas as the practices have changed a bit with different versions and iterations of Windows (as you alluded) but the advice dispensed doesn't always move with the times. And Windows should be able to manage it itself as-is to a hefty size (which may or may not be the case) provided you're not space-limited on the appropriate drive (which i'm not).

Even Windows managed, ensure the pagefile is on SSD and with extra space. Not HDD. That is a whole other issue.

Not HDD. That is a whole other issue. Which is why I qualified the statement. If Windows self-management of page files is borked then fine, but I can't find evidence that it is. Also, i've never had a problem with it previously in the context of DCS prior to the last few days since the last OB release, nor have I seen any evidence this crash is memory related yet. And if tinkering with such things was necessary for DCS it'd be in the requirements and not what appears to be a lot of 'it worked for me' posts with little evidence to back up WHY it was necessary to take matters out of the OS's hands. And yes, the swap file in on my system SSD which is NVMe (and the majority of drives on my system are either NVMe or SATA SSD with a couple of mech drives which just hold data).
