Hello,It occurs more frequently since I've upgraded to guacd 1.4.0, I see stalled process used a few days ago :
# ps auxf | grep guacdroot 548250 0.0 0.0 6196 716 pts/0 S+ 16:48 0:00 \_ grep guacd guacd 239034 0.0 0.6 1231968 13364 ?

All of them looks like : # grep 460026 /var/log/daemon.logMar 8 14:08:22 guacd-dc guacd[460026]: No security mode specified. Defaulting to security mode negotiation with server.

Print jobs are never closed at end, I think a normal job looks like : Print job created INFO:#011Print job created INFO:#011Created PDF filter process PID=460369 Created PDF filter process PID=460369 Print job closed INFO:#011Print job closed And the stalled processes last log line is : INFO:#011Created PDF filter process PID=460375 Maybe an issue with ghostscript ? It looks like two log lines are inverted : INFO:#011Created PDF filter process PID=460369 Created PDF filter process PID=460369 When it works, and once stalled : Created PDF filter process PID=460375 INFO:#011Created PDF filter process PID=460375As a workaround, I can kill processes individually, it does not seem to affect guacd behavior but it's a bit strange.
