Host profilling issue

Hello,

When trying to profile rogue hosts, I get the following error.

"Failed to Save Host - null"

This problem has been identified as a known issue in most versions, but I couldn't find a workaraund applied to the problem. Is there any documentation for this problem?

I thought I had this problem due to aging and deleted a sample host and tried again, but I still encountered the same error.

I also tested the expire and inactivity limit of a sample host indefinitely, but I couldn't find a solution.
