Hi Ghulam,
Virtuozzo, is an OS level based VPS. Which means available system
resources are shared between the VPS.
During Shutdown, a Java process is created; this in turn utilizes a
burst of RAM. So at that moment you have
3 JVMs running - TomcatA, TomcatB, and ShutdownA. That 3rd JVM may be
stretching the available resources
on your System. Now after TomcatA is completely shutdown, when you go to
shutdown TomcatB,
at that particular moment you have 2 JVMS (TomcatB,ShutdownB), which
your system is able to easily handle.
It is essentially a matter of available system RAM. You may want to
increase the RAM.

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....
