I am testing the dev/test 4.0.1 license version of lightstreamer server. It seems to me that the server process didn't stop running after 3.5 hours of execution, however, it stopped getting updates from data adapter. what I saw was:

ItemEventListener.update(string, IDictionary, bool)

stopped working, what I mean here is that client stopped getting pings from lightstreamer server. I looked into the log directory of lightstreamer server and didn't find anything.

what did I do wrong here?
