Podbot causing server to crash

[posse]

no i havent tested with disabling all plugins yet. i did disable unammo.amxx bcz it was giving some runtime errors so right now it is running with all custom plugins still but without unammo and with jason mode, if it crashes again i will disable all custom plugins and test again.

After a few days of testing and fiddling around with the bots I believe it is highly likely that the bots are not the sole reason for crash. I think it is the network lag occuring on the server and with the bots creating a lot more queries it is causing the HLDS process to overload and crash.

[KWo]

Does the crash happens at round start? If so - it might be something with model setting at players respawn (too many model changes at one frame - if there is many players on the server - above 20).

the crash doesnt happen at round start or at a particular map, i noticed that it happens as soon as the network lag starts.

This is what I got at the latest crash on a new server with no lag.

Saving experience data happens at map change, so Your crash happened before map change - at map end. But the first module pointed by backtrace is amxmodx_mm_i386.so, the next suspected is orpheu module. That seems to be nothing to podbot mm.
I would start with disabling orpheu, Zombie Swarm and round terminator (both they need that module). I would let the server to work 48hrs and see if the crash still happens or not.

[posse]

I dont know, do you know any other bots that would be more compatible with zombie mod? Theres so many on this forum, would any of the others potentially fare better?

[KWo]

Did You try the latest Zombie Plague instead Zombie Swarm? It doesn't need Orpheu module nor round_terminator plugin.
Podbot mm is the only maintained here bot for CS.

[posse]

Unfortunately the only reason my zombie server was created was for zombie swarm, I can't use zombie plague, my player base does not want it
