I do have a core dump. I will have to send you the link to it somewhere private.

still happens, it is very infrequent, but when it does, it is sometimes a few times in a row a few minutes after server starts back up each time. When i was testing with gmod dll modules, the libpthread error would happen when your thread closed without joining with main thread. This close can be a crash or legit close without a join. So if your module has no way of closing threads unexpectedly without joining then the thread must be crashing. This may even be caused by an outside source like a player trying to ddos sending a bad query packet or something.

The thread I create is being joined in the main thread, at module unloading, so I don't know how that part could be causing issues.

storm37000 commented 4 years ago

it means the thread is running into an unhandled exception somewhere and crashing, thus not being joined due to the unexpected crash.

I use it on two very populated servers and I never had a crash about this issue. Did you tried on a vanilla server ?

storm37000 commented 4 years ago

vanilla? this is for linux running on debian 10, the error stops altogether if i downgrade to the last functioning stable version (1.5.24)

Brskt commented 4 years ago

When I mean vanilla, I mean a server with no addons, nothing configured.

Did you tried on Deb 9 ? (cause we are on 9)

storm37000 commented 4 years ago

no, i have 10 which is the current stable version, im not ever going to downgrade as that would be too much of a pain/downtime. Also my testing indicated that this module is what is causing it.

danielga commented 4 years ago

What's your list of modules? Any custom made ones/available source code?

storm37000 commented 4 years ago

just this one, mysqloo, and mine(antifreeze, it is on github)

danielga commented 3 years ago

Closing issues related to old versions, new version is 1.5.32.
