IPv6: Badness in dst_release at include/net/dst.h:149
Last modified: 2007-11-30 17:07:28 EST
Description of problem:
Kernel starts complaining about
"Badness in dst_release at include/net/dst.h:149"
Version-Release number of selected component (if applicable):
Not possible to reproduce but happens every few weeks.
Steps to Reproduce:
1. Run linux, in this case a mailserver using both IPv4 and IPv6.
2. Eventually the kernel starts complaining and sendmail seems to have problems.
3. A reboot cures everything, until next time.
Sometimes the kernel has problems that seems to be IPv6 related. See attached
The machine is a Dell PowerEdge 1950.

Kernel log after problem occurs
We just had this problem happen today on a couple of our RHEL4 boxes too, though
they're both running a slightly older kernel (2.6.9-42.0.3.ELsmp). The dmesg
messages corresponded with periods of extremely high load.
Our kernel messages don't look exactly the same, so I'll attach ours too.

dmesg output with dst_badness messages
would you all mind please sending in sysreports? That would help track down
where the extra refcount decrement might be. Thanks!
The output of sysreport in this case is large (33MB) and contains a complete
configuration for the system in question - is the idea to attach this in public
to this bugreport?
yes, thats the idea. If you don't feel comfortable doing so, you can email them
to me instead.
Is this related to bug #167715 in any way?
It looks a lot like that to me. When is a fixed kernel going to appear?
Looks like it will be released with the 4.6 kernel update
