| Summary | 0004400: Crash ingame on UDPConnection operations |
|---|
| Description | This crash occurs fairly frequently. It may be due to code that I have on my libunwind feature branch, but I cannot see anything that would interfere with network code at all.
The crash usually happens inside the UDPConnection::SendIfNecessary() or UDPConnection::Flush() functions, but is not restricted to outgoing packet operations. For example, I have also seen similar issues with ProcessRawPacket(). |
|---|
| Steps To Reproduce | I get this bug in about 30% of the BA games that I play. I find that it happens more in larger games where there is generally more network traffic. It started happening as I work on the libunwind feature branch. I also did a kernel update recently but I can't imagine how that would interfere. |
|---|
| Additional Information | I have several stack traces of this bug, some produced with gdb and some produced with libunwind. It consistently happens with the UDPConnection class and usually involves corrupt containers but I have also seen failed assertions that arise from i.e.: badly numbered packets. It is related to 0004396. |
