[Xymon] Xymon hang

[Neil Simmonds]

Just had a bit of a weird one. A single Xymon server hung and wasn't
updating. When drilling down to an individual test we were just getting
a "Status not available" message on a white screen.

 

The only message we could find was in xymonlaunch.log and said "Could
not get shm of size 2097152: Invalid argument"

 

Issuing command ipcs -m gave the following.

A server reboot has fixed the problem but we'd like to try and find the
cause to try and make sure it doesn't happen again. Has anyone ever seen
this before?
