We had something similar but it was avrd that was hung up. stopltid asks
ltid to stop which in turns waits for it's children to stop. avrd and acsd
(if you use acsd) can get "stuck".

If you have a network problem acsd can hang and if you have a drive problem
(particularly fibre channel drives) then avrd can get stuck. We would end
up resetting the hung tape drive which allowed avrd to go which in turn
released ltid.

Look for processes that have the ltid process under the ppid (parent
process id).
ps -ef | grep 1234
1234 is the process number of ltid.

Cheers
Ed

We're using LTO gen II FC drives, and they seem to hang the FC connection
from time to time.  When this happens, ltid doesn't die or restart well
until the offending drive is power cycled.  I usually kill -9 for ltid
and then bp.kill_all the rest.
