Thanks. we limit mailboxes at 50MB. That is not too large IMO.
when the server gets bogged down like this, other people's web messaging just crawls. Also people who try to send or receive mail with POP3/SMTP get disconnected. Actually I was able to reproduce this behavior with Offline Synchronization in IE. I also specified to download up to 3 levels of links during the synch. As soon as I started downloading offline content, the CPU went up to 100%. As soon as I stopped, it went to normal. Maybe we need a patch? Something in the web messaging code that would prevent downloading offline content? -----Original Message----- From: Eric Shanbrom [mailto:[EMAIL PROTECTED]] Sent: Tuesday, December 03, 2002 4:44 PM To: [EMAIL PROTECTED] Subject: Re: [IMail Forum] Is DigExt driving my Imail server nuts? Actually what is probably happening is there are some really large mailboxes. These will chew up CPU cycles while reading the mailboxes in question. remedy, limit mailbox sizes to something manageable. If this isn't feasible then you will have to live with these times of usage. As long as it comes down on its own its not really a problem IMHO Eric S ----- Original Message ----- From: "Andrey Fyodorov" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, December 03, 2002 1:27 PM Subject: [IMail Forum] Is DigExt driving my Imail server nuts? 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?
