> expiry during recovery, which is a read operation, can lead to the need to modify the store. The recovery processing should take out a readwrite lock on the store.
> Issue arises for vm or file cursors as they replay messages from the store on restart to fill their caches. 
> This issue can be avoided by using the default Store cursor, so the workaround is to configure the store cursor, restart, and revert back to the chosen cursor.
