No ManagedConnections available

[beam36]

I read all through faq but I still can't find tje reason of my problem. I use JBOSS 4.0.3SP1 and I do not open my own connection at all. All db connection I use is totally via ejb(so i guess it can't be connection leak? except bug in jboss?) but I still got javax.ejb.FinderException: Find failed: org.jboss.util.NestedSQLException: No ManagedConnections available within configured blocking timeout ( 30000 [ms] ); - nested throwable: (javax.resource.ResourceException: No ManagedConnections available within configured blocking timeout ( 30000 [ms] ))

I'm in the middle of load testing. And when I load to about 100 user concurrently I will got a lot of above Exception. At first I tought connection is not enough so i change my max connection pool to 100(and 500 later) but I still get these exception and some sqlexception said that no more transaction slot. Is it possible that I really ran out of connection? I use weblogic at past and my db conf is the same. But with weblogic it's totally fine with just 100 user. (i use oracle 8i as my datasource) And as I already told that I'm not open my own connection at all. I use only via my datasource which bind by jboss. So I guess there should't be connection leak.

And theses exception keep coming up all the time. All of my processes mostly rollback because of these exceptions. Nothing seems to work after these exception start to happen.
