Exception on server.log file: Failed to expire ref in HornetQ

Issue

In one of our environmet(Env2- HQ Version 2.2.24+10743 patch) we are seeing below exceptions in server.log file. Could you pls take a look and let us know what could be causing all the exceptions that we see in env2. Multiple recycles have not worked and it seems to us that the data store is corrupted. However we can send/receive messages.
