This seems to be a different issue to me because I do not see anything happening in the _SecondaryIndex_ thread, and
the _MemtableReclaimMemory_ thread also does not seem to be stuck.
What I observe in the stack trace is that all but 2 of the Native transports are busy in the Auth path.
{code:java}
