Checking for Defunct Processes
1As root, enter
ps -ef | grep '<defunct>' | grep -v grep
.
The system lists any defunct processes (processes that have no parent). If
there are none, the prompt simply reappears. The example in Figure 4-8
shows three defunct processes.
Figure 4-8 Checking for defunct processes
2If there are defunct processes, note their process IDs (PIDs). The PID is
the first number after the process owner’s name. For instance, in the
example in Figure 4-8, the PID of the first defunct process is 123.
3Kill each defunct process by entering
kill PID
, where
PID
is the PID
number for the process.
4Enter
ps -ef | grep '<defunct>' | grep -v grep
again to confirm
that the processes were killed.
5If the basic kill command failed to kill a process, enter
kill -9 PID
.
Then check again to confirm that it was killed.
6Restart any processes that you had to kill, but that should be running.
# ps -ef|grep '<defunct>'|grep -v grep
jhaug 123 122 0 0:00 <defunct>
root 14919 377 0 0:00 <defunct>
jhaug 5807 5806 0 0:01 <defunct>
#
Caution! Be very careful when using the kill command and especially when using kill -9. Be
certain that you enter the correct PID. Never kill an sqlturbo process or you may
bring down the database.
