Hi,
I have been using amule-CVS since mid of September. And I have noted that amulegui have some problem with memory usage.
Sometimes, it start fine and fast, other times it first fill the RAM (521MB) and the swap space (512MB) and next it dies or starts randomly.
I have tried to connect from a windows machine with amulegui and seems to run fine (but I have not tested enough at the moment...). Maybe the problem is only in linux?
