KMS Crash
Hello,
today I had a manager (a little older one) who try the first time "such
modern thing like a online-conference".
I sent him an invitation-email and he made three (or more) times a
doube-click on the link.
I see his name a lot of in the client-list.
After that I see the red error "no multimedia" (or sth. like that).
I restarted KMS and Tomcat and all is OK again.
Is it possible to avoid that? Maybe only one connection per invitation?
Best regards,
René

Hello Rene,
If I do understand correctly you have
OM, DB, KMS ant TURN on single machine with 8GB RAM?
And 8 people in the room
My guess both memory and cpu might be troublemaker

We are using only internal on one VM, with several people. We did not noticed such problems.
What I can imagine is, that it is related to coturn and double natting.
We do have a second physical machine, connected direct to internet.
Also no issues here. We did some ISO audits with this over hours.
But the plan is once to get rid of the physical machine and use a DMZ.
So we need than also to run coturn…

What version of KMS are you using?
Does it have enough resources? (Ram, cpu)

Hello,
today I tried a webinar with 8 members - with me as moderator/presenter.
After a few minutes the viewers not see me. Behind the chat-Tab are the
red error-messages "Multimedia inaccessible".
But: at two viewers all is OK: They se my video and hear my voice.
I started my script to restart KMS, coturn and tomcat. The 2 viewers see
and hear me further, the other had no video, no audio
and, behind the chat-tab "Multimedia inaccessible".
I tried to restart separately KMS and coturn, cause it is fast to
restart this. (Tomcat neeeds after a reboot 15 minutes to come up, with
a restart it needs 30 seconds.)

OM should reconnect to KMS (please file JIRA, I'll check it)
According to limit login - I'm afraid it might produce much more bad
scenarious
What version of KMS are you using?
Does it have enough resources? (Ram, cpu)
