What's supposed to happen after that is that guacd will close the connection and then the child guacd process should terminate, which does not appear to be happening. I'm not entirely sure what those kernel messages mean. If you look in /var/log/messages and locate one of those lines that you posted above, are there any hints around those messages? Perhaps other lines that do not contain the PID, which would have been filtered out with your "grep" command? > It is on CENTOS 7.

I looked back in the message history and did not see that noted anywhere, though I so see libguac.so.17 which looks like the 1.2.0 version. And I assume this is the "stock" guacd (from the Guacamole website or Git repos) - you've not made any modifications/customizations to the code? Your original stack trace mentioned "accops-server", and I'm curious why that would show up in the stack track for guacd? I wonder if something else installed on the system has inserted itself into the dynamic loading order, and the libraries provided by that are causing problems?? -Nick
