So you should disconnect prior to hashing? What kind of advice or way to use eMule is that?
This obviously is a - strange and maybe rare - bug but nevertheless it's a bug and thus it should be fixed:yes:

can i agree with wizard of dos?

Anyway, i know that it's a lot of work... if you can fix it, else, np.

well, i never had to disconnect prior to any hashing using scarangel/ mephisto which uses just the same hashing algorithm... i am not saying there is certainly no bug but i think this is no pressing matter when it only occurs when using emule wrongly.
