Some will be waiting on monitors, some might actually be doing work, some might be stuck on I/O requests. You have to look at each call stack to see (a laborious process, unfortunately). It's often useful to take several thread dumps a few seconds apart and see what's changing and what isn't. > Could you explain why reading from /dev/random possibly > could be the case here? Because /dev/random (unlike /dev/urandom) can wait an arbitrarily long time to gather enough randomness before returning data. This is especially problematic on virtual machines running as servers, which have very little going on to generate entropy. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
