For information : the same happened to me with OM-5.0.0-M1: no connexion
was established with the Media Server anymore after a restart of my
server due to another reason.
This was the reason why I installed M3 (and installed KMS again), such
as the very beginning of my last topic:

I would say it is weird
All "occupied" resources are at minimum level after restart
Can you do multiple restarts and check if this issue is reproducible?
BTW what version of KMS are you using?

what user is used for KMS
according to the script, it seems there is a bug :(

Hi,
I run OpenMeetings M3 on a Ubuntu 18 Server wor two weeks
without problems.
Yesterday I did a reboot and openmeetings fails to connect to
the media server. It seems to be a problem with resource limits.
I can't remember I changed anything.
That's in the log of kurento after restart:

Sometimes it says there is an outof memory / resource limitation
and it's not able to open a new thread.

Any ideas for further checks what's wrong?
What kind of limits do you suggest in /etc/security/limits.conf ?
Btw, I used the tomcat3 init script Alvaro used in the tutorial.
Just saw the tomcat is still running as root, even if it should
run as nobody.
Maybe that's a problem also.
Kind regards
Marcus
