Description

When a Karaf instance is launched, it suddenly exited after about 50 days.

This issue is very similar to that of Apache Tomcat

https://issues.apache.org/bugzilla/show_bug.cgi?id=56684

In my case, I launched an instance at 7/22 10:35, but it stopped at 9/10 3:40. Here is the log when I encountered this issue:

Although its version is 2.2.10, I think maintained Karaf has this issues too.
