Constant DCs on EU-Sylvanas

I've been experiencing a lot of DCs the past two weeks. Every 15 minutes or so (sometimes more frequent, sometimes less) one or more of my slaves DC. The main character almost never DCs.

I have tried disabling some addons like Recount (which always causes trouble after patches ...), my Jamba has it's "boost communications" toggle turned off.

I'm using ISBoxer, the newest version, in stacked window mode.

I was wondering if anybody else is experiencing problem if this nature, perhaps on the same realm / battlehgroup. Or if there are some other addons that cause problems. I can post a list of addons if that is helpful. Everything is up-to-date by the way.

Tried disabling all addons, except Jamba, and it seems to help. Then I enabled Tidyplates and Bartender again, and the problem reappeared. Seems to be tidyplate's fault, although I don't really know why.
