That is indeed very useful. I had noticed a few times that the apache processes had not exhausted memory when the problem occurred - though usually they do exhaust memory. Your detective work is strong evidence that the memory problem is probably just another side effect of the real problem. Right now, we are in the process of moving c.h.o to a server with a more recent OS and more hardware capacity. That will take a little while, so in the meantime we are trying to use the available time most effectively by focusing mostly on server upgrade. We are hoping to keep the old server limping along in the meantime with band-aids like periodic restarts of apache. However, your work shows that this problem may not just go away by itself with the upgrade. Thanks for your help in further tracking down this problem. Let us know (possibly off list) if you have any more ideas. Regards, Yitz
