Hitting the same MemoryManagerClosedException with the #wikidata-primary-sources /search service, production deployment (mvn package).
Does not seem to affect the service response, which works fine.

The test deployment (mvn jetty:run) does not hit the exception.

Now that we have WDQS logs sent to logstash, I see a similar error. It sounds like the memory manager is closed while some code is still using it. Looking around in the code, I find AbstractRunningQuery.releaseNativeMemoryForQuery() where the doc is slightly scary. Beyond that, I have no idea what is going on, and if this is really an issue, or just a case of over verbose logging.

Stumbled upon this thread, didn't help, though:

Maybe the Blazegraph developers have an answer: could you please loop them in?
