Hi Trever,
It just happened again on another Linux media server
& looks like it's a "D" (uninterruptible sleep) :

(have to do 'pkill -9 strace' to exit it)

There's several 'Closed-wait' sessions which had been there for hours:
I also login to the remote server cellmgsvr (Win 2003 server) & issue
"netstat -ano" to search for pid of those sessions' pids (eg 3215, 3453,
2578) but none were there :
