BLACK ZONE alert on Stopping Tomcat Server

I have configured multiple tomcat servers on a remote linux machine, and monitors linux applications through Virtuozzo.

When I shutdown the TomcatA while TomcatB is running, the Virtuozzo shows the Black Zone alert (indicating that linux server is in serious state, related to system memory).

Similarly when I shutdown TomcatB while TomcatA is running, the same problem occurs.

But when the one Tomcat server is already stopped, and other Tomcat server is shutdown, then no problem occurs.

Any clue, that why Black Zone alert occurs.................or the Tomcat servers uses each other resources while being shutdown.

Any help will be appreciated....

The first wild guess I have is that you are using the same control port for both instances of Tomcat. If not that, what resources do these Tomcats share?

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link:
