Hello Mark,

I'm not very familiar with RPC Message Queuing, so I can't suggest a solution based on RPC specifics, but in order to avoid TerminateThread ()calls and at the same time to keep your algorithm you may try to use Fibers. Fibers are execution units that can be executed in the single thread context, i.e "thread in thread". Not sure if that can be a fine solution in your case, just giving an advice.

Hope this helps,
Hennadii.
