Our recently released modification (Fistful of Frags) is suffering some
stability issues. Hope someone can bring some light to these serious servers
crashes. I posted another similar issue in this list, and as I said before, I
never modified any part of the physics code. Now I'm starting to understand
what's going on, seems like a physic entity was removed, but server is still
trying to use it so finds a null pointer and crashes. Is that rigth?
These issues were noticed only during maximum stress, once the mod was
released. They may happen rarely or not, depends the way physics are stressed I
guess.
I'm using UTIL_Remove in several parts of the game, example: a cowboy hat is
created (falls to ground), and after some seconds is deleted. There are other
items deleted in a similar way. Should I use other method different from
UTIL_Remove?
And a last question. Can server performance ( low FPS) make these issues worse?
Because they tend to happen more in our own server, which sometimes is even
below 10 FPS.
Hope this helps, these are 3 different call stacks we are seeing repitedly. If
you need any other info plz let me know.
