One of the two lagged interfaces dropped from ACTIVE,COLLECTING,DISTRIBUTING to just ACTIVE, and it logged "Interface sto= pped DISTRIBUTING, possible flapping". At that exact time, the client's mount h= ung. That's highly suspicious. I can't find any evidence for that happening dur= ing previous events, however. But it does suggest that something in the network stack is not handling packet loss well. --=20 You are receiving this mail because: You are the assignee for the bug.=
