A channel agent is a well-behaved application that will not toast your queue manager. On the other hand, a poorly coded application running FASTPATH (hint) will almost certainly toast your queue manager!

Channel programs/threads quite often run user exits, and these can introduce stability risk if they have bugs. Do not use FASTPATH channels if you are running user exits, unless you are fully confident that those exits are bug-free. |

And to make things totally clear: memory leaks are BUGS. Although way more difficult to find and fix than any other type of code error. So when you use a user exit, not only do you need to take care of multithreading issues you need also to keep in mind memory management.
Have fun
