[comp.protocols.tcp-ip] question about hanging sendmail communication

douglis@MINT.BERKELEY.EDU (Fred Douglis) (05/10/89)

We're experiencing a problem sending mail to an internet host
(decwrl.dec.com) -- the symptom is that the mailer hangs for a long
time and then complains "reply: read error", apparently in the phase
just after it sends the body of the message.  I heard that about the
same time we started having this problem on Sprite, a small number of
Suns running SunOS 3.2 had the same problem, and I was told that
upgrading the kernel to 3.4 fixed the problem.  This is why I believe
the problem might have something to do with the TCP connection (since
just about everything at user level is the same, but the kernel is
new).

Can anyone possibly shed some light on this?  If anyone else has
experience trouble completing sendmail connections, to decwrl or to
any other hosts, I'd like to hear how they fixed the problem.  I'd be
most grateful for any suggestions.  Please include me directly in any
replies, since I'm not on the mailing list.
