Operating Systems HP-UX [Solved] How to remove / kill defunct processess? Post 302411070 by jgt on Wednesday 7th of April 2010 01:26:44 PM
Old 04-07-2010
This issue seems to be caused by users closing Windows terminal emulation sessions without first signing off, (clicking on the X before exiting the session.)
On SCO systems, these "ghost" sessions tend to consume all the available CPU trying to re-connect.
I wrote the following script to deal with this issue, but it should be used with caution.
On SCO systems telnet sessions are named ttypnn, on HP-UX it appears they are named pts/nnn.

Code:
#!/bin/ksh
if [ $# -eq 0 ]
then
echo Usage is delete.ghosts  Y or N
exit 1
fi
ps -leaf |grep ttyp >/tmp/ps.list
who >/tmp/user.list
LIST=; export LIST
separator=" "
while read a tty c 
do
LIST=$LIST$separator$tty
separator=" |"
done </tmp/user.list
grep -v "?" </tmp/ps.list |grep -v root |\
grep -E -v "$LIST" >/tmp/ghost.list
while read a b user pid e f
do
if [ $1 = Y ]
then
echo for real $user $pid
echo kill -9 $pid
#kill -9 $pid
else
echo test run $user $pid
echo kill -9 $pid
fi
done </tmp/ghost.list
#
