panics deciphering VMSTAT output
I've been trying to track down a regular, but not manually reproducible crash in 3.0-BETA (19990205). I can't get a crashdump due to a DSCHECK negative number bug. I think my swap space of 3+GB is too large for it. So, I've been having it send me the output of vmstat -m every 15 minutes to try to track it down. The couple of times I've seen the panic message on the console, it was typically, but not always: pipeinit: cannot allocate pipe - out of kvm It has been happening approximately every 6 hours on a heavily loaded server with 100+ chrooted daemons and NFS. So, in short, so that I can compare my vmstat outputs to the one I captured 3 minutes before the last crash, can anyone tell me what the vmstat entries mean? :) A quick legend or tutorial would be helpful, and I'll turn it into a FAQ for the documentation project, too. -Troy Cobb Circle Net, Inc. http://www.circle.net To Unsubscribe: send mail to majord...@freebsd.org with unsubscribe freebsd-current in the body of the message
