Version 3.0.x is not supported anymore
You can check DB pool options in persistence.xml and try to tune it

Re: Connection Pooling Issue on OpenMeeting

Hmm,

Your initial question was about connection pooling
Connection pooling is being used for DB connections only

Now you are asking about "maximum limit OM supports for active connection"
I guess this is regarding browser-to-server connections?
The answer is not that simple

you can easily find "maximum number of connections Tomcat can handle" (here
is the example [1])
BUT big numbers will require well configured cluster and load balancer

Second part of your question is "50000 user joins the event" this is
actually not about number of connections
Your bandwidth will be the bottleneck: [2]
