We are geeting "Service temporary unavailable" mesggage very often if the concurancy increases more than 500 users in our application. We are using Jboss 4.2.2 and SQL server 2005 as DB. As per our observastion this error is because of high load. Our application concurrancy will exceed more than 1000. Please help us to fix this issue. I have attached teh errror screen.

Thanks
