Hazel Crashing

Hazel has been crashing and requiring manual restart 10+ times a day. If you want I can dump the whole log, but I think these errors are relevant:

2016-07-26 08:10:20.034 hazelworker[23620] Caught exception while getting events from scheduler: [NSMachPort
sendBeforeDate:] destination port invalid
2016-07-26 08:10:20.034 hazelworker[23620] Could not get file events from scheduler.
2016-07-26 08:10:20.039 hazelworker[23620] [METRICS] Caught exception sending metrics to scheduler: [NSMachPort
sendBeforeDate:] destination port invalid

Any suggestions?

Can you post the actual crash? Under your home folder, go to Library/Logs/DiagnosticReports

See if you can find any crashes for any Hazel-related processes.

I am able to find Hazel Helper Files in that folder (see below). However it must be noted that they don't seem to correlate with crashes very accurately (i.e the most recent file is a few weeks old and hazel has crashed nearly 100 times SINCE then).

You'll need to find dumps for the more recent crashes. How are you assessing that it is crashing? Also, check the regular system logs, not the Hazel-specific ones and see if you can find anything there.
