Update from ESX 4.0.0 398348 to ESX 4.0.0 721907 sfcb Problem with HTTP header

Hello,

we did an ESX-Upgrade from 4.0.0 Build 398348 to 4.0.0 Build 721907 and now we have the following log-entry in /var/log/messages

Aug  2 09:37:38 vmware07 sfcb[7694]: -#- HTTP header command is not expected

This entry occurs every 10 minutes.

On the other servers (Build 398348) the error doesn't occur.

Do we have to worry about this? Is it possible to disable this?

Thanks in advance

Regards

Sven
