Anyone know how to dig something useful out of the current state the buffer cache is in? I know how to find out what vnodes are locked but don't know how to go from that to see what underlying buffers are causing the problem. I should be able to cause a dump of the machine as well but it has 2Gb of memory in it so transferring the dump to someone other than me who could look at it might be painful... -- Ken Smith - From there to here, from here to | kensmith_at_cse.buffalo.edu there, funny things are everywhere. | - Theodore Geisel |Received on Thu Feb 05 2004 - 10:06:13 UTC
