The system was up for 2+ months and x11vnc was launched maybe hundreds of times. Today it failed all of a sudden: > shmget() failed: No space left on device x11vnc is launched as a new process every time the user connects to the loc= al display. This means that when x11vnc finishes it doesn't release resources that shmget(2) allocates. Ultimately shmget(2) becomes a time bomb which blows up eventually and x11v= nc (and probably all other software that uses shmget(2)) becomes unusable until the system is rebooted.
