One of my Imail servers is experiencing abnormally high CPU utilization periods (100% flat for a few minutes). Most utilization comes from WebMessaging.
We have already replaced the dual 650MHz CPUs with dual 850MHz. I have moved the Web folder to another spindle. I also moved the SPOOL directory to another spindle. I have defragged the drives. It helped somewhat but still once in a while the server gets bogged down. I have been looking at the logs and it seems that the high CPU utilization coincides with events like this: 20021203 120027 Info - 200.61.69.184 Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt) http://mail.xxxxxxxxx.xxx/ POST /login.cgi HTTP/1.0. 20021203 120029 Info - 216.170.73.98 Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt) http://mail.xxxxxx.xxx/Xxxxxxxxxxxxxxxxxx/readmail.5178.cgi?mbx=Main&msgsort=1 GET /Xxxxxxxxxxxxxxxxx/forward.gif HTTP/1.0. My understanding that DigExt means that the user has made this web page favorite and available offline. So the whole site gets downloaded each time the user logs in. Am I thinking in the right direction? Is there a way to kill DigExt?
