I've got the same problem on debian sid with the amule debs since 1.1.0. It won't work well after some time.
First, it'll use 100% CPU for about two seconds, then low CPU for about 2 seconds and so on. When amule uses 100% CPU, not even typing text into config dialog widgets works (it will be shown after 2 seconds).
Then, after some hours, it'll use 100% CPU and will take 5-10 seconds to respond to clicks or redraw the UI.
Downloads drop down, Upload goes to less than 1/2 (which usually never happens), in sweeps and pauses.
Upload is being shown wrong (10K, and it IS 3-5K then), Download seems okay.
BUT: I've got a selfcompiled 1.1.0, which didn't have this problem when I used it, but I just tested it and it does now. Could it be that the evil CPU eating bug is in a library amule uses?
Because the UI doesn't respond when it sweeps the CPU, maybe wx? Wouldn't be the first time...
Debian sid, Athlon XP 1700, HTB Traffic shaper.
It worked before 1.1.0.
