Razor -agent log Invalid Arguments

[Jim Flowers]

I seem to be getting a fair number of SA timeouts (3%) so I looked at this
log and was surprised to see a lot of Unable to connect Reason: Invalid
Argument messages.

Is this a known problem/bug and if so what is the fix?

mailscanner-4.26.7 with razor-agents-2.36_2 on FreeBSD 4.9-STABLE
