Surprised that lowering the priority didn’t help - so now I need to think about other options. It feels like something when the carriers can use all the cores that the poller is prevented from running - like some sort of lock being held by the carrier/vt and do it thrashes around until it eventually gets a chance.

With pollerMode=2 then the the work is done on virtual threads so I
assume you don't see the master poller stealing CPU cycles.<br>

In any case, what you describe sounds a bit like bursty usage where
all FJP workers are scanning for work before parking, and/or
something else that may be macOS specific when running out of some
resource. I suspect tuning the networking params to remove the
errors/timeouts might make it a bit easier to study.<br>
