Looks like the ht object kept by the NamespaceIndex for a Database never gets freed.
Memory leaks from DatabaseHolder::getOrCreate() and related
Any updates on this?
No - buts its incredibly small.
Do you think its impacting you?
Not sure what the impact could be. We perform db updates every 5 mins, then there are queries and maintenance tasks. Just wanted to estimate that as I'm looking as memory footprint for our system.
Do you call closeDatabase? if not, then this won't impact you at all.
