memory allocation error: block too big
(tail call): ?
I get this addon on certain boss fights in Naxx (Maex, and Noth) and then my pitbull frames and bartender go bonkers . I have Ace3 installed, so should I even still have Ace2 installed? Any help or insight is appreciated.
An easy way to tell if you still need Ace2 is to disable it and log in. You'll immediately be flooded with errors from any addons you have that use Ace2 or that use libraries that use AceLibrary. If there are no errors, then you don't have any, and you can get rid of it. However, given the fact that you're asking this question, you should probably just be using the default download packages with embedded libraries, in which case you don't need Ace2 or Ace3 installed standalone.
As for your error, there is a lengthy thread about this floating around on these forums. The general consensus seemed to be that CowTip was the most common cause of this problem. If you use CowTip, try disabling it for your next Naxx run and see if the error stops happening. If you don't use CowTip, post a list of addons you do use.
try getting ride of Ace2* LibRock* as much possible like many does and you should less be overhelmed of strange errors, Ace2 is no more updated and ckknight does't provide decent support to its stuffs so find something other than using Quartz CowTips Fubar and all old stuff like that, there is very well done alternatives outta there.
