Klondike "hangs" after being started for some time

[reyalpsirc]

Each time I start the klodinke server, it works well for sometime but, after one/two hours, it just stops responding...

I know that the process is running:

And that it is indeed listening on port 8080:

But is is just not answering back:

And the logs do not have any info. The last entries in it are:

Can this be related to the App Pool Advanced Configuration?
If so, how do I enable the following on an Ubuntu machine?

• Make sure Maximum Worker Processes is set to 1
• Make sure Disable Overlapped Recycle is set to true
