So I'm using this in my factory (1.14) on a server and it seems to stop working after about an hour. When that happens even separate sorting chest arrays stop sorting.

Still unable to reproduce this, if anyone knows a setup to consistently reproduce the issue with it'll be a big help.

It was using sorting iron chests, and we nailed it down to destination chests filling in a different chunk, it would not go looking for new destinations for things, and it would clog up.

Is there anything suspicious in the logs?

It's on a server so that'll take some time to check.

woot, ok server access attained, anything I should be looking for?

Pretty much anything that contains "refinedrelocation" or "Exception" could be useful. Are you using Sorting Connectors or how were your chests connected?

ok, so it seems to result from the intersection of matching chest priorities, across chunks.

Closing this for now since there hasn't been any recent reports of issues like this.
