Hi All,
I could see messages are piling up on input queue of a message flow
Ipprocs is 1 and it is dataflowengine. message flow is able to pick up the messages and writing to failure queue.

however messages are continously pilig up in input queue.
Messages are slowly processed by flow. What could be the reason for slow process? is there any limit for processing messsages?

Poorly written error handling code? Failure is a timeout against a database so messages sit for 60/120 seconds until the timeout occurs?

There's no limit per se - how many threads is the flow using? Or are messages single threaded through the flow?

It would help if you gave us details of the errors experienced by the message that leads them to the failure queue.
