app is deployed on websphere  application server 6.1

Does it happen only when both run at the same time or even if the first one is not doing anything and only the second one is running? Is it always the same the one that is failing? Had you try redeploying the war (thinking here that maybe you are not running the same code exactly?)? Do you call the method with the same parameters?

No they are not running the same time. First one runs fine. And second one throws this. After that first one fails as well. Second on always fails.

Thanks

Sounds like a restriction of the number of connections between the servers. Let me think where this might have happened....  It is definitely not a code issue
