See warning message: "LRU while use (use-count=1). Consider increasing session-count.

The LRU must be sized large enough to hold all running sessions (i.e. those currently serving a request.).

The default is fairly low (4096). If a server has more active sessions than that, it needs to change the session-count to something much large.
