> Could you try procstat -kk on the process, does that shed any light?
When I was trying `procstat -k', I was getting the message:
PID TID COMM TDNAME
KSTACK
procstat: sysctl: kern.proc.kstack unavailable
procstat: options DDB or options STACK required in kernel
That was with a single `-k'. I can't do anything now, because -- after
an attempt to start `systat 1 -vm' -- the system hosed and would not
start new processes. The existing ones, such as the cvs-over ssh are
stuck in:
load: 0.00 cmd: ssh 59098 [proctree] 0.41u 0.17s 0% 0k
Yours,
