Re: strange hung processes

If it's not sensitive information, what does this show?

>>    lsof | grep 'pid of hung process'
>>
From my systems guy:

in /proc

codd 13262 # cat status     {proc "filesystem"}
Name:   postmaster
State:  D (disk sleep)

Because of the "D" state, it can't be killed as it is not interuptible
(waiting on IO ?).
