Обсуждение: Error msg.

Hi all,

I've been getting strange error messages from a new installation of
postgres.  Occasionally, it prints out:

"invalid packet length"

What does this mean?  Should I worry?

Thanx in advance,

It means the postmaster got a message with an unreasonable packet length
(first word of the connect request message is supposed to be its total
length, IIRC).  Yes, I'd wonder about it too.  Got any broken clients,
portscanners hitting 5432, etc?
