16237 user 25 0 438m 364m 28m R 62.0 18.0 3:12.91 ld-linux.so.2
After kill,
ps aux returns the following
user 16237 32.4 19.3 477072 401280 ? S 23:17 3:27 /lib/ld-linux.so.2 /opt/Adobe/Reader8/Reader/intellinux/bin/acroread --display :0.0 -progressPipe 3 -exitPipe 4
This is the acroread 8.1.2 problem definitely. I found the debate about that problem on the
http://blogs.adobe.com/acroread/2007/09/known_issues_with_adobe_reader_1.html
I just turn off two options, I hope it helps...

The problem creates many zombie processes as
user 1328 0.0 0.0 0 0 ? Z 11:15 0:11 [ld-linux.so.2] <defunct>
user 21611 0.0 0.0 0 0 ? Z 13:29 0:04 [ld-linux.so.2] <defunct>
user 24009 0.0 0.0 0 0 ? Z 15:11 0:04 [ld-linux.so.2] <defunct>
user 25269 0.2 0.0 0 0 ? Z 16:06 0:04 [ld-linux.so.2] <defunct>
defunct process can be killed by
ps -ef | grep defunct | awk '{ print $3 }' | xargs kill -9
The above command is dangerous (commented by one person)
"ps -ef | grep defunct | awk '{ print $3 }' | xargs kill -9" is
dangerous because ps will sometimes list this command line itself
(after all, it contains the string "defunct" in the call to grep). The
kill command will then abort its own parent process, which is the
current shell in most cases.
