Red Hat 8 was using a totally different thread library. I'm sure this behavioral difference is tied to NPTL (easy way to test this too, just disable NPTL and try it). top is invariably doing the wrong thing. It has a lovely history in this regard. > If I need to understand the memory usage on my system I need to know the *real* > memory > used, not allocated.

Allocated is useful in some circumstances, used is useful in others. However, what your notion of "used" is may vary from the kernel's. As such, things like RSS and VSIZE are the much more reliable measures of what's going on with your system, or just have your program track it's allocations so it can report information to you directly. Anyway, this is not really a Java discussion, but a Linux discussion that is best had with those that maintain the relevant components. -- Christopher Smith <[EMAIL PROTECTED]> ---------------------------------------------------------------------- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
