Looks like a segfault did occur according to dmesg. This is the output: [ 386.612493] guacd[4711]: segfault at 7fadd03c45f0 ip 00007fadd03c45f0 sp 00007fadc06dcc68 error 14 likely on CPU 1 (core 0, socket 0) [ 386.612510] Code: Unable to access opcode bytes at 0x7fadd03c45c6.
The Gucamole server does infact have a Firewall performing SSL inspection on the traffic. This could be the culprit, since you mention it I suppose you have had issues with this in the past?

I'm not sure those events are actually related - I suspect something else is closing down the connections. You might want to check and see if guacd is crashing - check your system's coredump/segfault management facility and make sure it isn't getting handled by that automatically in the background. You can also check "dmesg" output and see if you see any messages that indicate guacd segfaults. Also, might want to make sure nothing is interfering between guacd and the remote servers - any sort of deep packet inspection, IDS/IPS, etc. -Nick ________________________________ AVISO DE CONFIDENCIALIDAD: El contenido de este correo, asi como sus archivos adjuntos estan protegidos por el secreto profesional, son confidenciales y son para el uso exclusivo del (de los) destinatario(s) deseado(s).
