[Wrapper-user] Limit on started JVMs under NT Service

[Christian C. <car...@ap...>]

Hi everyone,

I tried to install several NT services using the Java Service Wrapper.
Each of these services executes a JAVA program, spanning a couple of JVMs
(using basically the exec method from Runtime class).

Let say:
Service NT_SVC1 : A java application, starting 8 children JVMs
Service NT_SVC2 : A java application, starting 5 children JVMs
Service NT_SVC3 : A java application, starting 5 children JVMs


The problem I encounter is that the system refuses to start more than 16
JVMs. The 17th is killed as soon as it has been started
No matter the Wrapper started first, I'm always getting 16 JVM started.

In my example : starting NT_SVC1, then NT_SVC2, then NT_SVC3, only 3 JVMs
from NT_SVC3 are started.
If I kill 1 JVM from NT_SVC1 and I restart NT_SVC3, I notice 1 more JVM is
started from NT_SVC3.

Is there any limitation in Java Service Wrapper, or in NT services that I
reached ?

Any help would be appreciated.

Best regards,
Christian Cardinale
