I'm confused on your report. The subject line says this happens on restart; but the numbered steps to reproduce the problem are blank, and under "When does the problem NOT occur" you said "When server rebooting"? Does the problem occur during restart, or at some other time? Either way, you need to edit your report to fix it, because it's contradicting itself right now.
I traced the crash to a routine that sends HUD updates to a client. Although the crash is consistently happening in this same spot based on the traces you posted, I can see no way for this list to have gotten corrupted. Any heap corruption, especially occurring as a result of running out of memory, should be more varied in its results. If this issue happens on reboot (we still need to clear that up), does it happen consistently? | |
Nope, this is not happens consistently, only when server at high load, i think. Other two reports dont have other logs, im sorry for this. Reproducing problem looks like: rebooting server when its on high load and then sometimes we got crash. I can add more logs, when server got crashed in future.
| |
So to clarify, this happens only during a reboot? If so you should edit your report, because the "Numbered steps" portion is incorrect and so is the "When does the problem NOT occur" answer.
| |
Yes, after reboot and when server starts load a map. Edited topic a little.
| |
Looking into this further, I wonder if the problem is that a client is disconnecting under these circumstances--which it could if your reboot load is heavy. I added another sanity check that might well prevent this problem in 511.1374.
