Just by chance try turning off the RAID read-adhead and write-back cache. I've seen problems with some RAID cards that cause wired things on web servers, that said I've never had a problem with IMail and my DELL PERC RAID card. You may also want to make sure Hyper-Threading is turned off. Had problems on some of my Citrix Servers with Windows 2000 and Hyper-Threading being slow ... once disabled the server ran much better.

This all started about ten months ago, when our web messaging would crawl to a halt whenever an email msg was sent to one of our [EMAIL PROTECTED] (approx 2000 addresses large). At that point, Web Messaging was at least stable, slow but did not receive page cannot be displayed. Back then we were running v 8.05 HF2. The Imail support suggested that we switch from a MS Access DB to MS SQL to improve performance. So, we did last fall (Sept 2004) and ever since then users are experiencing page can not be displayed errors randomly. Sometimes it is when they are first logging in, other times it is when they have clicked on reply, or clicked on address book, or clicked send message, or tried to delete msgs. I had a case open with them since Oct 3rd, 2004 and after numerous suggestions from them, (tuning down the parameters of SQL to only use 1 processor and 1 Gb of RAM, adjusting the page file size to triple that of the actual RAM)by late November the only answer I could get wa s, "Have you tried upgrading to v 8.14". Th So, we upgraded to 8.14, the problem was then pronounced by a factor of ten. This is when students and faculty started complaining. Most staff are using an email client, so they are not affected. Still dealing with Imail support, I granted them remote access into the box so they could check things out. After that they had said everything looks fine, but then suggested that we switch back to MS Access because our DB is only 5 MB and that the overhead of SQL out weighed the performance gain. I formatted the server on Jan17th and then switched back to MS Access. The latest solution that I have tried is purchasing a 10/100 server class 3Com NIC (ref an earlier thread "Imail and NIC issues" as well as a suggestion from Herschel Jones) With the 3com NIC I have noticed a big change myself. In fact I have only received Page can not be displayed once since the install, it has been about three days. But others are still having the problem. It is very inconsistent, I myself could go 2,3,4 days and not have any errors, but then the very next day be fighting "page not displayed" My latest experiment was at 3:00 AM in the morning. I turned off POP3 and IMAP, and rebooted the box. Used TCPview to see how many active connections the box had, it had less than a page worth (15-20). Still I was getting page cannot be displayed. So, anyone have something that I should try or look at? I am surprised it has gone on this long, but now the Administration is asking that we look into a different email system, even though we just put Imail in in Aug 2003. An error that keeps popping up in the log "10054 malicious..." which on the imail support site says to disable any power mangmt on the NIC, which has been done.
