Can you reproduce this? Or was this a "once in a lifetime" crash? If it is reproduceable, please increase the logging to verb 7 to better understand what it might be doing there.

Also being able to run this in gdb and ask for a backtrace when it crashes would be highly appreciated (so we know in which function it crashes)

[ordex]

A potential fix was pushed here: http://gerrit.openvpn.net/c/openvpn/+/1737
@vitalik6243 @GubernievS would you be able to patch your OpenVPN and re-test the same scenario?
Meanwhile I am trying to reproduce it here, but it's not a super-easy-to-catch race condition.

I installed this patch. I'll watch for the problem to reoccur. It may take some time. The issue is intermittent.

The error was reproduced on the latest version 2.7.5

[ordex]

@GubernievS thanks, but what's the purpose of telling us that openvpn still crashes without having the fix applied?

[GubernievS]

i say about - this is no "once in a lifetime" crash and no repair in last version

[ordex]

no repair in last version

yeah, the fix hasn't been merged yet. We were hoping to gather some feedback.

[ordex]

Hi @GubernievS thanks for reporting the crash.

Before the first line of the first log, were there more lines like
Jul 09 10:33:25 ratty-magenta.ptr.network kernel: antizapret-udp: deleting peer with id Y, reason X
Just to understand OpenVPN was going through a "mass notification" event.

Also, was this run performed with OpenVPN patched with the patch linked above?

Thanks!

[GubernievS]

1. Yes
   I see many messages 'deleting peer with id Y, reason X' befor and after segfault error
   Approximately 300 users openvpn connected

2. No
   Fix not installed
