StackOverflowError when process looping to much

[billbaroud]

Hi guys,

I have the following process, that is looping and get messages from an 'incoming queue', delete the messages found and wait 5 seconds if no message is found.

Problem: if my queue is filled with more than 30 messages, the workflow will loop 30 times and I get the following error:

Exception in thread "pool-1-thread-2" java.lang.StackOverflowError

Musst I set a wait timer between each and every loop ?

Thanks

Hi,

You could make the "Delete message…" service task asynchronous.
That would solve this issue I think.

Best regards,
