JBoss remoting will try a certain number of times (default 30) with a pause of 1 second if the pool is full to wait for a connection to be returned. This means by default invocations will wait 30 seconds for a connection to be returned before throwing an exception. You can increase this period by setting the attribute "numberOfRetries" on the connector config. This basically equates to the number of seconds to wait before barfing. You could set this to a high value (few minutes) in your case. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4017685#...
