Hello there,
I have a strange problem with synchronization of CDNS server for one of ours Expand servers.

Here is a part of operator.log where performed action is described:

Here is the action information (taken from Expand's Action Log):
Action info:

</packet>

Action Input:
<packet version="2.3.0.10">

</packet>

Advanced Taskman output:

<packet version="0.1.1.0">
<result>

<errtxt>Action executed successfully</errtxt>
</result>
</packet>

Is this means that CDNS server is unsynchronized after a successful execution of sync task?

Any help will be appreciated.
Thank you in advance.
