Nick Couchman commented on GUACAMOLE-1016:
------------------------------------------

[~Chamberland]: Can you please provide more detail on this - under what conditions you see the segfault?

You can bump up the logging level for guacd by running it with the "-L debug" flag.  Log messages are, by default, logged to your normal syslog environment - so, /var/log/messages or journalctl on most systems.  If you're running in docker they'll  For a segfault I would also suggest running gdb with guacd so that you can get the stack trace.  You'd do something like:

gdb /path/to/guacd -L debug -f
set follow-fork-mode child
go

And then when it segfaults you should get the full stack trace.
