Could give me some additional information:
- Did it occur while running a peer?
- How long did it run before the crash happened?
- Which plugins did you have enabled?
- Was your peer reachable from the Internet?

Sorry, don't recall at all.

Had a peer with revision 32024 running for ~ 3 days with:

[transport]
plugins = udp tcp https_client https_server

No crashes (coredumps) after that time ...

Please give me feedback if it happens again and re-open the bug. At the moment I cannot reproduce and the bug is quite old does not appear on my system...

Perhaps it was related to a bug like 0003245 crashing transport and after that a invalid outdated session was given to transport...
