Hello,

Unfortunately, one week later I have a lot of stalled processes, started days ago :

How can I troubleshoot why they are stalled ?

Regards.

Mind retesting with a build of guacamole-server from git master or "staging/1.5.0"? Changes were recently merged that should address this.

    I'm seeking directions to narrow the issue. Some usage of
    ghostscript worked fine, other hangs.

    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=460375

    As a workaround, I can kill processes individually, it does not
    seem to affect guacd behavior but it's a bit strange.

    Regards.
