Thanks again, Emmanuel. I'll try using VisualVM to generate a memory dump. I think we close the sessions correctly, but, when profiling with JProfiler, I always get a lot of SocketIoSession objects on the heap. Do you think the number of IoThreads used by the Acceptors and Connectors could influence the memory consumption? We are using 5 IoThreads for the acceptor and 5 for the connector. We have about 4 million email accounts, but about 5% of it read messages through IMAP protocol.
I'll see if I can prepare some user code and the memory dump to help you.

AFAIR, I was using 1.1.7, and I run the test exchanging around 70 > messages (LDAP), with a client and 100 threads.
