The problem is that you are running the Panther version of aMule, which is PowerPC-only. On your Intel Mac, this version has to run through the Rosetta emulation layer, which makes aMule run very unstable.
The fix is easy -- just get the Tiger Universal Binary version of aMule from
here and everything will be well.
Since this seems to be happening more frequently lately, I have added a note to the Panther version in the download section to discourage Intel Mac users from downloading it.
