Description

During the unload process (DeltaSessionManager) we write our current sessions to disk and delete them from our session region. It's possible for a session to be evicted while this process is ongoing which results in an EntryNotFound exception which interrupts the process of clearing out the region.

We can fix this by catching the exception and ignoring it - there is no circumstance where we want to change behavior if an entry is evicted right as we go to delete it in this process.
