Nick Couchman commented on GUACAMOLE-816:
-----------------------------------------

A couple of follow-up questions for you:
- Are you using SSL/TLS with VNC?
- Can you provide a stacktrace of the dump?

> There are no troubles in the functions of guacamole. But there are some log entries in our syslog file:
> hostname kernel: [790049.145417] guacd[4661]: segfault at 78 ip 00007f70a34fee99 sp 00007ffe7fda2b50 error 4 in libguac-client-vnc.so.0.0.0[7f70a34f4000+f000]
> hostname guacd[4661]: Client disconnected
> The SSH and VNC connections are working without any problems.
> It seems that the segfault occurs on a client disconnect.
