I took down Zimbra about a week and a half ago and didn't disable the BES before doing so and Calendar items stopped synchronizing. This seems to always happen if I jiggle the handle on Zimbra without first asking the BES for permission first ...
Anyways, so I reboot the BES and I could have had a turtle move faster.
CalHelper had eaten almost all the available memory on the machine, but was slowly regurgitating it until everything was back to normal.
I checked online and found this article on the problem ... but I haven't done anything to the CDO.dll file to warrant that problem.
Anyone else have this problem while working with the BES?
