Description John Caruso 2008-05-16 14:48:32 EDT
Description of problem:
The kernel occasionally produces the message "KERNEL: assertion (cnt <=
tcp_get_pcount(&tp->packets_out)) failed at net/ipv4/tcp_input.c (1553)".

Version-Release number of selected component (if applicable):
(it's also occurred on other kernels, though I'm not sure exactly which
ones...this is just the latest)

How reproducible:
Happens at random times, very infrequently (once every few months)

Steps to Reproduce:

Actual results:
Error message.

Expected results:
No error message.

Additional info:
We've seen this message occur on three different web servers over the past few
months (8/31/2007, 1/3/2008, and 5/13/2008).  It isn't accompanied by any
obvious misbehavior, though we've rebooted the servers in question after they
produced the message just to be on the safe side.  This isn't a serious problem
by any means, but I'm reporting it because I couldn't find another bug report
for it.

We're seeing this also.
this box serves nfs as a veritas cluster.
Due to the high bandwidth, we;re seeing half a dozen of these each day.
We are ignoring them.

RHEL4 has entered the Extended Life Phase. There will be no more minor releases.

I'm closing this bug due to inactivity.

Please reopen and provide an explanation if you need this issue to be addressed in RHEL4. Please note that only security and critical bugfixes are considered at this point.
