grsecurity forums

Somebody mind telling me how to fix this?

This occurred primarily after a gentoo update (I forgot which one). Restarted using gradm but that was to no avail. Any possible way to fix this other than a reboot?

I think this happens when the file is still in use but overwritten. Restart whatever service got updated and that should fix it I think.

Such a simple solution, don't know why I hadn't thought of it, heh. Many thanks for the help

What version of grsecurity are you using, and on what kernel? You shouldn't have "(deleted)" appearing in any of your pathnames.

I've seen these messages after upgrading a running service. It happens with 2.6.21.6-grsec, and I'm pretty sure it has been like that for a while. I never thought anything of it, because the service needs restarted anyway.

It's linux-2.4.34, grsec 2.1.10

mdadm had just been upgraded. After following the advice of the previous poster, the error had disappeared.

This will be fixed in grsecurity 2.1.11. A patch for 2.4.35 already exists in ~spender and 2.6.22 will follow soon. The problem manifests itself only when the parent directory of a removed file is also removed.

Ah. Thanks spender.
