> Date: 2005-08-16 02:19Sender: cheungmingLogged In: YES user_id=896657 this is caused by the bug fix on #1088486. the reason isthat a network io is differ from disk io. for diskio, theworker stops and then wait current io ends and quits, whichis pretty reasonable. but for network worker, it is possiblethat there is always 1 io unfinished for certain unknownreason, then it dead loop there.
