      Description

      two brokers bridged together, producers and consumers spread across the two.

      After about 8 hours or so processing ~30 messages/second, amq logs a java.io.IOException, shuts down, and is restarted where it seems to continue on its way:

      We'd been running 5.9.1 on these exact same servers for many months using leveldb without this problem. Upgraded to 5.14.0 yesterday and hit it twice already. I tried wiping out the leveldb database before starting as a test and it still reoccurred.

      Interesting thing is, it happened on both servers within a couple minutes of each other, even though they had quite different uptimes.
