You should have said that you were using NFS. Locking on NFS is hit-or-miss at times and we would have told you to suspect that as a likely cause and try running with the session store on a local disk. If you are using a load balancer, all you need to do is arrange for load balancing to be deterministic, either by session token (ideal) or client address, and then each worker only needs to care about its user's sessions.
