I have a most interesting situation that just manifested itself this = morning in a way I could begin to diagnose. The system runs 8.2-P3 and = has no users, just one process that runs 24x7. Its been running since = 8.2 was first released. Every now and then the process becomes = non-responsive. Today it managed to spit out an error that the system = had run out of swap space before it hung. This is quite interesting in that there are 5.5GB of free memory. The = only time that changes is at 3 am when the various periodic processes = run. However, I don=E2=80=99t suspect those as I have numerous other = systems that have considerably less memory and higher usage that do not = experience this issue. I have increased the swap space to prevent this = issue, but something must be going bonkers to cause the swap space to = get used. Usually there are only 15MB used. Every time the system = notifies me that it has the problem, by the time I can look at it, swap = is back to normal. I have never been able to catch the system with more = than 15 MB used. Is there any way after the fact to figure out what was = using the swap? I suspect not, but thought I=E2=80=99d ask just in case = I have overlooked something.
