Occasional crash with 3.0.19 #2732
How to reproduce the issue
There's no trigger I'm aware of, or no special configuration. It just happens after a couple of weeks. It does happen occasionally. It happened with earlier releases too, I never got to capturing the event: but now I have a core dump :-)
(While it happened with earlier releases, somewhere above 3.0.15 I think, the exact same configuration did run without issues somewhere in the past. And while this is a busy server, the crashes are really occasional.)
I'm using the 3.0.19 docker container these days, on an Ubuntu 18.04 LTS host. (Previously it crashed with self-compiled releases and no containers too.) Looking at system graphs, I see no issues with resources (memory, disk spikes) whatsoever at the time of the crash. (It was actually at a quiet time, in the middle of the night).
This is a proxy server (it does no EAP, just RADIUS/UDP and TLS, sqlite and rlm_cache_rbtree).
Full backtrace from LLDB or GDB
Hope this gives some direction to look at. If there's a new event (hopefully similar) I'll add it to this issue, but for this crash I was already waiting for over 6 weeks. (And before that, core dumps were not happening for various reasons.)
