[jboss-user] [JBoss Messaging] - Any Limit on the Number of connection to JBoss Messaging Ser

Hi Just wanted to know is there is any limit in creating connection object(with invocation of start method on the connection object) to JBoss Messaging. We are using jboss-messaging-1.0.1.GA. 1) I just wrote a program which created a connection object of around 2000.While going thru the log ,i cud able to get some exception.those exceptions did not stop the execution of the program in creating 2000 connection object.I did not do any operation on those connection object. I just created and invoked start method on it. Attached the exception seen at client and server side. do let me know your fruitful reply!!
