Peter, Obviously I didn't fully put on my thinking cap yesterday when I mentioned the LOCAL LOCK.
I was attempting to think of what might be causing the poster's perceived condition of SRB #2 not appearing to run in the address space of the PAUSED global SRB #1. Your comment seems to be backing my understanding that once SRB #1 did the PAUSE, SRB #2, or any other qualifying unit of work, was free to run in the address space subject to normal dispatching rules. Michel, You may want to run this situation on a test machine and start a GTF trace and see what is happening from that. It should answer the question about if the second SRB is being dispatched or not.

The system will no longer treat it as such after the pause. Chris mentioned the local lock. I'm not sure why. You can't pause a work unit that is holding the local lock. Obviously some other running work unit could hold the local lock and thus prevent an SRB scheduled with LLOCK=YES from beginning. In the scenario posed SRB 1 scheduled to address space A pauses SRB 2 was scheduled to address space A (from anywhere) SRB 2 will run, according to normal dispatch priority rules.
