i was solo and it happens. Now i was dual boxing and had my shaman OoP healing me. Was there a change not long ago that shows inc heals? could that off been it?
Only if the rise in memory usage was attributed to PitBull (or PitBull_VisualHeal if you have your modules disembedded). If it was not accounted for, as in the OP's example, then it's not the VisualHeal module.
I have reverted one of the recent changes to PitBull which could possibly have been the one responsible for this problem. Please update to the latest revision and let us know if the memory leaks are still there.
I disabled half of my addons as discribed but I couldn't locate the leak. If Pitbull really is the culprit, the latest change didn't fix it, after some battlegrounds this morning my memory still increases constantly. Only seems to happen on my rogue alt... I have no idea what's causing the leak but it still sucks.
so far seems to be working. I'm currently having to test it on a different computer (at work) so I'll definitely know when i go home tonight. Both computers are set up the exact same way in regards to mods (just copied the WTF/Interface folder) so i don't see why they would act differently so good chance is you found the problem.
