attached an updated (by me) copy of tomcat4, however, memory is not
consumed if OM started after a reboot (2G max for 3 classes, 5 students
each, audio only), but if multiple stop and start is done, all memory is
consumed.

98% of RAM might be an issue
was the memory consumed by java process?
What are the `-Xmx` and `-Xms` parameters for OM?

I experienced this after upgrading to a 5.0.1 snapshot and was
about to follow up a response to Maxim. Not at a computer at the
moment but I experienced exactly the same. I am using Ubuntu
18.04 on AWS with 8 gigs ram. When SSH’ing to my server (with only
one user logged in (me) I noticed RAM usage was 98%...
I downgraded to OM 5 M4 and everything is fine again (but lack the
advantages of the snapshot upgrade)... RAM usage dropped a lot
also... a lot!
Will take some time to compare tomcat3 and tomcat4 on startup,
folder permissions and differences between OM 5 M4 and recent
snapshot.
All the best,
Denis.
