Java APIs

Hi all,

We have a problem on production installation of our product on Solaris paltfroms: jvm takes more (much more) RAM than defined in -Xmx param and without any OutOfMemory exceptions. (how itt possible at all ?)

The only JNI call in application is SAP interface connector, but application uses a lot of Runtime.exec() calls.

Is it possible to have such kind of "leaks" in java using JNI or Runtime.exec()?

I will be very appreciate for any tip how to find the root of this problem and how we can fix it ?
