Trouble!

I agree.
While I don't think the exactly same problem with 2.6.1 has been
reported yet, there was work in fixing some related issues
with SMTP session caching in later versions of amavisd, along
with hardening code in this area, so switching to 2.6.4 would
be strongly recommended. If that doesn't fix the problem,
I'd certainly want to know about it - your last log was exactly
what I'd want to see if trouble persists.
