Hi Brian This boils down to a network contention issue – that you are maxing out the network resources and GPFS is waiting.
Now- digging deeper into why, that’s a larger issue. I’m still struggling with this myself. It takes a lot of digging into network stats, utilization, dropped packets, etc. It could be at the server/client or elsewhere in the network.

Lots of waiters in deadlock with "waiting for exclusive use of connection for sending msg". Did you ever determine a fix / cause for that? I see your previous comments below.
