What to do with zombies on Websphere MQ V7.0.1.7, amqrmppa processes?

I did the following command on Linux to list 8 zombies:

-bash-3.2$ ps -ef | grep defunct
mqm 6625 3925 0 Feb27 ? 00:00:36 [amqrmppa] <defunct>
mqm 9190 3925 0 Feb25 ? 00:00:47 [amqrmppa] <defunct>
mqm 11842 3925 0 Feb22 ? 00:00:41 [amqrmppa] <defunct>
mqm 15018 3925 0 Feb20 ? 00:00:32 [amqrmppa] <defunct>
mqm 18089 3925 0 Feb22 ? 00:00:52 [amqrmppa] <defunct>
mqm 22594 3925 0 08:55 ? 00:00:00 [amqrmppa] <defunct>
mqm 23613 3925 0 Feb26 ? 00:00:44 [amqrmppa] <defunct>
mqm 26172 26153 0 14:16 pts/2 00:00:00 grep defunct
mqm 27270 3925 0 Feb21 ? 00:00:35 [amqrmppa] <defunct>

Do I need to kill them or not?
Did anyone solve this with installing refresh pack?

Are you running the WMB on top of WMQ. If yes what user id does the broker run under? What is the primary group of the user running the broker?

We are not running WMB. On this queue manager it's connected WAS with server-connection channel.

I restarted qmgr and at this moment there are no zombies.
As soon as they will appear again I'll issue the pstack command against the parent process.
