OK as you like :-) > If we think we may have a hang at Tue Apr 18, 9:38, is there any specific > logging we should set up on a server at that time? Maybe detailed truss output if it happens, to get all arguments and a few things like this. Unfortunately for now I don't see an easy way to reset the kqueue fd and reinitialize all events from scratch (though it's possible, just requires quite some code and will come with some bugs). > is it worth setting at > least one server to have nokqueue set at that time? Well, possibly if you have multiple servers and all of them die at the same time, that could avoid a complete outage. And maybe nothing will happen, it was a pure guess from me but given that these ones more or less match issues we've had a long time ago with looping timers, I would not be surprized if it happens this way.
