The other HT&CAS server node doesn't get this error logged regularly.

So far there is no user complained about anything related to this issue that I know of.

Does this also related to this error that is logged in another HT&CAS server role ? as I logged in this thread: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_28647132.html

This issue may occurs if exchange version are inconsistent.

Do you have same rollup / service pack applied on all the servers ?

I recommend you keep all of the exchange server versions the same and check the result.

Have you also verified the roll up installed for Exchange 2010 ?.

Commented:
no roll up is installed, so all servers are all still on SP3:

2x Mailbox servers (no DAG)
2x HT-CAS servers

Have you run the Exchange BPA to see if it finds any problems? When is the first this error started in your logs??? Does it correlate with any chances in your environment?

ok, so in this case I've visitedhttp://support.microsoft.com/kb/2665115 but it suggest Exchange Server 2010 SP2 UR 1, mine is now on SP3.
Commented:
I am reading two interesting article on this error...

One stats this is fixed in rollup 4 but you are already running SP3.. The other error can accure from a problem mailbox with invalid characters.
