[posila][0.16.24] Crashes randomly

[adamcharnock]

I've been noticing a lot of crashes of late and I have not been able to pin it down to any particular action on my part. Log attached. I'll attach more logs as it happens.

Here is the previous log too, also a recent crash.

And again, at roughy the same point as the very first log I posted (one I reloaded from a recent autosave)

[adamcharnock]

And one more. Ask if you want any more, otherwise I'll assume this is enough to go on.

The crashes are all over random places, leading me to believe there is something wrong with your computer. If you upload your save, I can see if it crashes for me too.

Other possibility is that bug in disabling trains stop through circuit network or destroying it in 0.16.24 doesn't crash the game on mac immediatelly and randomly corrupts memory instead.

Ok, one last one. The game is definitely sometimes dying when trying to autosave, but looking at the logs that doesn't seem to be the only reason for the crashes.

Try to run memtest or some other software testing RAM over night

[adamcharnock]

Done. All tests passed ok.

I ran this on a MacBook Pro 15". I booted into recovery mode and used the binary from www.memtestosx.org (I failed to create a bootable usb from memtest.org). Screenshot attached.

Thank you for looking into this, factorio has always been very stable for me until now.

Hi Again,

This still seems to be happening upon save. Latest log attached. I've got a 100mb save game stashed away if you want it.

Whoop, I think I've managed to recreate this semi-reliably. Save and mods directory is as follows:

https://www.dropbox.com/sh/0wbcmzpfnix2 ... 9Bi0a?dl=0

Open this, then save then game around 20-40 seconds later. Most of the time I find it crashes.

I tried to save every second from 15 to 40 seconds after loading and didn't have crash. Then I tried to load the save and save it at random 20 - 30 seconds after loading. Then I let the save run for some time. No crashes. You computer might be overheating.

memory may have checked out ok. what about crunching numbers and putting the CPU & Memory under load?
try running Prime95 'just stress testing' blend test for a few hours.
