Description

If the persistent cache is severely broken (after ouf memory for example), in some cases the store is closed, but there is still a risk to get many log message (mainly null pointer exceptions) saying "Could not retrieve the map size". This needs to be avoided. Possibly the cache files should be removed in such cases, and the cache re-created.
