High CPU load by ocsmanager

[MuPp3t33r]

Hi all

I've been experiencing a high CPU load and have managed to identify ocsmanager as the likely culprit.
When checking it's logs, something that stands out is "Exception: Cannot find exchange first organization unit in samba database"

This keeps repeating itself every couple of seconds so I figure its simply retrying the same operation constantly, but at this stage I'm unsure of what steps I might take to resolve it.

I've included a sample of the output log below, if it's not enough then I can provide a more complete log

My environment:
Zentyal 4.2.2 - fully up to date
Installed modules - Network, Firewall, DNS, Logs, NTP, VPN, Domain Controller, Mail, OpenChange

Log obtained from: /var/log/ocsmanager/ocsmanager.log
