 I've been experiencing an issue with pidgin on ubuntu 11.04 for a while
 now.. I decided to download and compile my a newer version. I just did
 this with 2.8.0. I setup a single AOL account and am seeing the same
 issue.

 Debug does not say anything.. the cpu usage starts a while after the
 "dns[18825]: nobody needs me" line.

 Debug:

 strace of what is happening when pidgin starts using 100% cpu. After that
 the same EAGAIN message repeats continuously:
