Without a coredump it will be super difficult to reproduce. It looks like it is related to the webserver though, so maybe tcpdump could help you there aswell if the time can be predicted.

That looks like the backtrace was ran before the segmentation fault. You need to run it afterwards.

I attach gdb to the running process

ps -C tvheadend

gdb --tui -p pid

but 100%

need redaction

Thread 26 "tvh:epgdata" received signal SIGSEGV, Segmentation fault.
__memcmp_sse4_1 () at ../sysdeps/x86_64/multiarch/memcmp-sse4.S:794

You backtraced a running process, there's no point in doing that in this case. You need to continue, wait for the error to occur and then bt full (and coredump as there might be more information needed later on).

So after the output in the last post you would have to run "bt full" and create a core file.

Is this still in issue? From the backtrace it looks like some HTTP Request caused this. I would like to get it fixed if this is still happening.

Will check with new commits, and report.
