I had a problem with similar symptoms on FreeBSD where a kernel bug
caused a protocol violation. I am using SSL, and messages like "Host is
down" appeared in the server logs. I'm not sure what exactly happens
when not using SSL.

The problem is described here:

Thanks to AndrewSN for tracking it down originally.

However, you need to post more information to determine the real cause.
