Created attachment 10080 [details]
improve_error_message_for_MDB_MAP_FULL.patch

The UCR variable listener/cache/mdb/maxsize is not well documented. In case an administrator finds

cache.c:469:cache_update_entry_in_transaction mdb_put: failed: MDB_MAP_FULL: Environment mapsize limit reached (-30792) 

in the listener.log s/he will not know what to do to fix this.

The attached (untested) patch shows how this could be improved in the code.
