Re: LOG: unexpected EOF within message length word

1)
I am using postgres 7.4 version.

2)I have sent tusc o/p along with first mail.however I will attch it
once again.

3)the following code works fine in HP-UX PA machines.but not in HP-UX IA
machines.
I meant the maxiumum data that we can insert into IA machines
is 40760.if we make it to 40764 then the code breaks.
Here also size of array matters.and all code is same.
It just contain some additional info of size 25 charecters/column
which I feel not relevant to problem.

4)I have changed default setting and made it as TCP
still problem persists.
Cud u please eloborate more on this topic(using TCP vs Unix Socket)

Thx ,
Waiting for u'r reply,
Prasanna.

The code you posted works for me with PostgreSQL 8.0.3 on FreeBSD
4.11-STABLE/i386 and Solaris 9/sparc. I don't know if there are any
issues with HP-UX IA; is there anything else different about the two
environments? What versions of PostgreSQL are you using?

Aside from not being a complete program, the code you posted doesn't
quite match the problem description you gave initially: you said you
could send 40760 bytes, but that sending 40764 bytes caused the
connection to hang. Is that an accurate description? The code you
posted sends 3000000 bytes and several additional columns that might not
be relevant to the problem.

I haven't seen that -- did you send it to the mailing list?

How much data is written before this happens? Are you using a local
(Unix socket) connection or a TCP connection? If the latter, have you
run a sniffer on the connection to see if it shows anything unusual
(e.g., a closed window)?
