Yes. The linux emulator emulates the clone() based threads of Linux kernels from 2.2 through 2.4 (NPTL of 2.6 would only show up as one thread). In that approach each thread shows up as a separate process. If you don't want this then switch to the native 1.4.2 JDK and you'll only see the one process. -- Greg Lewis Email : glewis@eyesbeyond.com Eyes Beyond Web : http://www.eyesbeyond.com Information Technology FreeBSD : glewis@FreeBSD.org
