Prusaslicer crashes repeatedly when slicing multiple models
I was getting the following event log after Prusaslicer crashed.

I frequently load models of fine mesh for various WW2 models that I am printing for friends. I can print several copies of a single model but Prusaslicer is crashing to the desktop if I try to print several models at once. I've been working around the crash issue by doing single models, but if I am loading too many different meshes at same time, can I at least get warning message from Prusaslicer about being overloaded before crashing?
Thanks,
Jamie
RE:
Two suggestions. If allowable (by license, etc), upload a PrusaSlicer 3mf project file that you can get to crash here. You'll need to first zip it, otherwise this forum will silently delete it from your post. (Annoying, I know.) About all we regular users can do is verify that the bug also happens on our machines.
Developers don't regularly lurk here, so they likely won't see your bug report. Crashes should be reported on GitHub. In PrusaSlicer's Help menu there is a "Report an Issue" selection. This pulls opens the GitHub new issue page in your browser. Select "Bug Report" after logging into GitHub (or creating a free account) and follow the instructions in the reporting template. The more you can fill in the requested information, the better the devs will have to find your bug and hopefully squash it for the next release.

From your log entry I'm guessing you use Windows, I haven't used Windows for many years so I can't help with the specifics.
Fine meshes are memory hogs. Increase the allocation of ram to the PrusaSlicer task or at least make sure there are no other tasks in memory competing for space. Make sure you have plenty of swap space on a fast drive. Consider installing more RAM in your computer.
Uploading a 3mf is usually the best way to have a project debugged but if it is a memory allocation issue then be aware that different operating systems handle excess memory demand differently (Eg., some will throw an error, some will just drop the task silently and write a log, others will swap to disk and slow down drastically finally finishing in a few days.) and different users will have more or less ram available so for some the crash may come sooner and for others never.
You already have the best answer: slice them individually. If you want to fill the bed make sure all the other parts are simple meshes, perhaps low-poly.
Cheerio,
