Description Christian Mollekopf 2013-04-19 11:13:09 UTC 
I recently had an imap resource get into a state, where it would just endlessly accumulate memory. I finally killed it at 4GB, after which the problem did not reappear. I attached a debugger and tried to figure out what's going on, but didnt really figure out all that much, I'll attach a bunch of gathered backtraces though (I simply attached the debugger, stopped the resource at random points, and took a backtrace, not sure if it's of any use). Unfortunately I couldn't figure out where all the memory was going (tell me if you know how to figure that out without restarting the application).

Reproducible: Couldn't Reproduce

Can you get a massif report ?

Nope, still can't reproduce it and didn't run into the issue for some time now.

The IMAP resource has a new maintainer, reassigning to him.
