I've just checked how long the
online server example is running and found out that it is
running for 2 months now.
This is not something simple to achieve as every small memory leak will grow over time and will eventually kill the server process. In fact in the first few versions of jServer library there were memory issues that caused the process to run out of memory after a few days.
The server is quite active especially since the release of the
custom push framework solution.
