The use of ps and top as a way of determining memory use can be misleading for processes with many threads. Although not totally accurate, for a process with more than 5 threads the ps or top value should be divided by the number of threads to get the actual amount of memory used. Also, consider that the ps/top value is all memory used by the process not just the heap. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
