In v1.69, if I just start BitComet only with pure download tasks that I know have LT upload seeders, even just a few like 15 tasks, BitComet would program crash after 5 minutes to 10 minutes. I have done a few tests and that seems to be the conclusion.
If I mix those LT download tasks with download tasks I don't know if there are LT seeders, then BitComet seems stable.
