Defunct processes with Linux Host agent?

Oddly enough, I've seen a few of these problems in the last few days. I guess we are having a run on them, which is how things seem to happen in support. Lots of the same issues from different customers in different regions. I can't explain it, but that's what happens.

If you do a ps -efl output you'll probably see zombies like so;

0 Z root 29905 29733 0 85 0 - 0 do_exi May24 ? 00:00:00 [sh ]
0 Z root 22119 29733 0 84 0 - 0 do_exi May31 ? 00:00:00 [sh ]
0 Z root 21339 29733 0 84 0 - 0 do_exi Jun07 ? 00:00:00 [sh ]
0 Z root 5702 29733 0 83 0 - 0 do_exi Jun14 ? 00:00:00 [sh ]

Not exact of course, but if you stop the MLRAGENT process, which is the host agent on the host. You can do this from ControlCenter Console. You will find as soon as you do all the zombie processes will terminate and get cleaned up.

Soon as it's started again you will get 2 zombie processes, as the agent when started attempts a discovery, and then each night when the discovery DCP runs you will get 2 more and onward it will go until agent is restarted.

This is a known issue on ControlCenter 5.2 SP4 and was resolved with Hotfix/Patch #3713

Unfortunately I cannot confirm if this is available on Powerlink, as it appears my profile has been messed with.

Please quote this number to the person currently assigned with your SR and if they need any assistance, tell them to contact me internally.

EDIT:

I managed to track down the open ticket and who currently owns it. I've since updated the open ticket to indicate the same details above. I've emailed the current owner the hotfix details and left you a voicemail to indicate I've since made the link between this query here and the open ticket. Thanks
