Sessions not closed properly

Hi!

In an EP7 (SP12) we're facing the problem that it seems impossible sometimes to clean up old sessions properly.

In the default trace of the dispatchernode we see errors like:

Error in resource clean up for a disconnected client

java.lang.NullPointerException

preceded by:

Connection is NOT emoved! serverToConnections = ...

Anybody ever experienced such a situation? Could this be leading to hang-situations that we're facing?

Thanks for your answers,

Jörg
