I've had a CPU bound task https://lhcathome.cern.ch/lhcathome/result.php?resultid=429904502 running for days with no apparent forward progress having this initial log line:

===> [runRivet] Mon Oct 27 09:00:12 AM UTC 2025 [boinc pp z1j 7000 250 - sherpa 1.2.3 default 100000 346]

The tail of the log has been

Event 37100 ( 9m 41s elapsed / 16m 26s left ) -> ETA: Mon Oct 27 09:31
37100 events processed
Event 37200 ( 9m 43s elapsed / 16m 24s left ) -> ETA: Mon Oct 27 09:31
37200 events processed

for more than 2 days without change. I'll abort the task shortly to free up resources for other things.
My question is should I do anything differently? Is this an expected occurrence?

Yes, this task got stuck and should be cancelled.
Unlike other Theory tasks Sherpas are known to have a higher risk for this.
