I was going through KB172813 and I looked in one of the MDBDATA folders. I saw that there were STF files several MB in size being created, deleted, created, etc. over and over. A quick search told me that these were related to either IMAP or POP accounts. I checked the two IMAP users (Mac users BTW) that had logged on the server since I had restarted it and had them close their email programs. The problem stopped immediately.
I narrowed the problem down to a user that just received a new workstation yesterday. I need to check out the settings on their mail program to see if I can see what the problem is. Has anyone else seen this happen before? We have several Mac users that use IMAP and I have never seen this issue before. I don't set up our Mac workstations, so it may just be a simple misconfiguration, but I am surprised at how swiftly it brought our server to its knees.

I can see nothing out of the ordinary happening on the server that would give me any clue as to where to start looking. There is no anti-virus running on the server. Internet email is forwarded from our Xwall server which is now showing any unusual activity. There are no huge log files and the message queues appear fine. There is nothing unusual in the event logs. The full backup I ran last night went just fine. Since the high CPU usage start, clients can connect just fine, but responsiveness is less than normal. I restarted the server last night and for the first few hours afterwards it seemed to be running fine. When I got in this morning, the high CPU usage was back. This is a single server in it's own site and does not communicate with any other Exchange servers. It is running on NT 4.0 SP6a+ and has all the Exchange service packs and rollups that I am aware of. The version of the store.exe file is 5.5.2658.4. Nothing has been changed on the server in the recent past. Any ideas where I can start trying to figure this out? ----------------------- Chuck Parkey Creative Teaching Press _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
