Unknown source engine linux server crash - IVP failed at

Having a pretty weird issue with a linux hosted gmod server crashing with the error “IVP Failed at …/ivp_utility/ivu_vhash.cxx 157”

from what I’ve read, its physics related and usually happens when items manage to fall into the void but so far I’ve seen nothing directly in the logs before the crash that would cause it. I even tried spawning stuff out of the map and the game seems to take care of it by removing it

" Crazy origin on entity [144][item]
Origin: [-5159.025391, 5089.977539, -16384.107422]

No idea how to analyze a gmod crash dump. What are some options for debugging or preventing a crash like this?

Crazy physics happening often causes instability and then leads to crashing. From my guess based on the error, the item entity is probably spawning on an uneven surface of the map, falling through and going into the void. If you have any addons that spawn items around the map naturally, you’ll want to reset the spawns and put it on straight surfaces ( or contact the addon creator to add some units upward incase it is in the world ).

Regardless, crashing should be reported to the right place. I’d recommend you use this guide to diagnose it fully and, if not solved be the end, send it out.

I used these two addons for many years to avoid this kind of crashes:

Follow up, did any of these work? If so make sure to mark it as a solution

VPhysics airbag seems to be working to prevent it. I’d say this is solved.

Thanks.
