Hello Shawn,

The logs appear useless, they are littered with these:

Regarding the versions, it is a bit hard to recall but i do no thing i have seen this on 7.2, most certainly not on 7.1.

We operate three distinct type of Solr collections, they only share the same Zookeeper quorum. The other two collections do not seem to have this problem, but i don't restart those as often as i restart this collection, as i am STILL trying to REPRODUCE the dreaded memory leak i reported having on 7.3 about two weeks ago. Sorry, but i drives me nuts!

Thanks,
Markus
