Re: 100% server CPU usage
Vishal- For now the problem seems to be solved. I'm watching it carefully over the next few days to see if that's really the case. I set symantec antivirus corporate edition to exclude any .tbb and .tbi files and performance dramatically improved immediately. I still think this is one of those dreaded interactions between TB and antivirus software where each mail database was being scanned on TB launch and any sort of action: get new mail, create new message, move to new folder, etc). It's strange, though, that when we uninstalled SAVCE from the server we were still seeing TB using 100% of the CPU resources. Reminds me of the Zone Alarm mess. -Mark Wieder Using The Bat! v1.63 Beta/7 on Windows 2000 5.0 Build 2195 Service Pack 2 -- Current version is 1.62r | "Using TBUDL" information: http://www.silverstones.com/thebat/TBUDLInfo.html

I was on broadband when this happened to me. More importantly, I don't think the email was particularly big, so timeout issues weren't the problem.

I store attachments externally here - I'll have to log in and check the client site to see how I set that up. Unfortunately there's no way to tell TB to extract attachments retroactively - it's only from the time you change the option, so there's no way to cut down on the size of the existing mailboxes. I'm somewhat miffed that the "corporate edition" AV doesn't have anywhere near the granularity of the configuration options of the personal edition. At least not that I can find. -Mark Wieder Using The Bat! v1.63 Beta/7 on Windows 2000 5.0 Build 2195 Service Pack 2 -- Current version is 1.62r | "Using TBUDL" information: http://www.silverstones.com/thebat/TBUDLInfo.html

I've run into the "rogue email" situation before, but only on a dialup connection where we hit some timeout before a huge email could be collected completely. This is on broadband and the reports I'm getting are that it happens pretty much constantly. I logged in using terminal services and had a hard time getting anything done because so much of the CPU resources were devoted to processing mail. -Mark Wieder Using The Bat! v1.63 Beta/7 on Windows 2000 5.0 Build 2195 Service Pack 2 -- Current version is 1.62r | "Using TBUDL" information: http://www.silverstones.com/thebat/TBUDLInfo.html

100% server CPU usage
Bats- I'm seeing TB causing 100% server CPU usage on a client's win2k system. Here's my theory about what's going on. Any comments? They've got Norton Antivirus Corporate edition installed on the server. The corporate edition doesn't seem to be very configurable (I didn't do the installation, so I don't have the docs to check with). You seem to be able to configure it to exclude certain files or folders, or to do entire system scans at a given time, or to scan removeable devices as an option. There are about a dozen email accounts that need checking on a regular basis during the day. They got set to check for new mail every one minute (I recommended 5 minute cycles, but let's talk about the one minute cycle for now). This combination of things seems deadly and here's what I think: TB launches the Connection Center and starts checking for new mail. When a new message comes in TB stuffs it into a temp directory. Norton, noticing that a new file has just appeared, scans the file. If all is well, TB integrates the new message into the message database file. Norton, noticing that the message database has changed, checks the database file. This can take a long time, depending on the size of the file. Now control returns to TB, which Norton has had in blocking mode all this time, and the second message comes in. So... reality check time... does this make sense? Has anyone else run into this? Is anyone else running a combination of win2k, TB, and Norton corporate edition? Is there somewhere else I might think of checking to see why TB is pegging at 100% CPU cycles while checking email? We can certainly configure Norton not to check the email directory and the temp directory, which should eliminate this problem, but then the incoming emails wouldn't be virus-checked. There doesn't seem to be an option to check emails, incoming or outgoing. I wasn't the consultant who came in and installed Norton in the first place, I just inherited it. And, yes, I *have* recommended NOD32. I have this same setup here (running NOD32 instead of Norton) and when the Connection Center comes up I see my CPU cycles spiking to 10% from a nominal level of 2-5%. The only thing that regularly uses 100% is setiathome, but that's what it's designed to do (using background cycles). -Mark Wieder Using The Bat! v1.63 Beta/7 on Windows 2000 5.0 Build 2195 Service Pack 2 Current version is 1.62r | "Using TBUDL" information: http://www.silverstones.com/thebat/TBUDLInfo.html
