Description of problem:
I noticed the following problem.
SMTP connections for e-mail which contained attachements (above 100kB)
were impossible. Connections were established, a few pewrcent of
e-mail was getting transferred, and then the connection was getting
very-very slow (few packets per minute).

I tried various sendmail versions (including the original Fedora's).
There's no problem with sending data with FTP i.e. I only noticed
problems with e-mails.

The problem is definitely with the kernel or network interface module.
Kernel 2.6.7-1.494.2.2
Network card is Broadcom Corporation NetXtreme BCM5702X Gigabit Ethernet.
Module used is tg3.
The card is running at 100Mbps since the switch is not 1Gbit capable.

Everything worked fine with previous kernel 2.6.6-1.435.2.1






Version-Release number of selected component (if applicable):
kernel-2.6.7-1.494.2.2

How reproducible:
Always

Steps to Reproduce:
1. send e-mail with attachement through sendmail
2.
3.
    

Actual Results:  the e-mail transfer fails after few kBytes get through

Expected Results:  the e-mail should be transfered without problems
it works OK when I got back to previous kernel 2.6.6-1.435.2.1

fixed in 2.6.9 based kernel update ?

Comment 2 Dave Jones 2005-04-16 04:51:58 UTC
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.
