Description

This is not easy to reproduce I haven't been able to simplify it down from our code to recreate it but I can reliably cause it to happen. Basically if you hit a camel-sjms route with a spike of load from nothing and have a bunch of .toD("dynamic-${route}") it can create more connections than the pool allows then when a connection is returned it is closed and one of the routes will be using a session with a closed connection and will not work until it is restarted.
The code in question:
