Comment 5 Bob Gustafson 2008-06-27 16:00:23 UTC 
I don't know if this is related, but I updated to a new kernel (Fed8) and this
kernel is unusable because of a memory leak. I have 3GB and it takes about 10-20
minutes to fill, then I need to reboot.

I went back a kernel using the boot/grub.conf option.

The kernel with a problem is 2.6.25.6-27.fc8
The kernel that runs ok   is 2.6.25.4-10.fc8

System is x86_64 and processor is Intel Pentium Dual CPU E2160 @1.80Ghz

Stopped most servers (httpd, asterisk, bluetooth,dhdpd, sepostgresql, tomcat)
for above tests (and currently).

I can provide additional information - let me know.
Comment 6 Mark J. Cox 2008-07-23 13:05:34 UTC 
text used in RHSA:

* a possible kernel memory leak was found in the Linux kernel Simple
Internet Transition (SIT) INET6 implementation. This could allow a local
unprivileged user to cause a denial of service. (CVE-2008-2136, Important)
