hi there,

i'm running ubuntu 10.04 server on a customly built box and i'm getting a lot of messages concerning memory leaks whenever i
* upgrade kernel headers
* remove old kernel images
* update grub

i believe that this is only concerning grub, as apt calls grub scripts when setting up new kernel images

some messages after dist-upgrade:

I've been having the same error every time update-grub is executed whether during kernel upgrade or manually.

I am running Ubuntu Server 10.04 LTS and I seem to be having the same issue.

When I run update-grub or even the last time I ran apt-get dist-upgrade I get memory leak errors.

Here is the result from the last time I ran update-grub:

Here is another thread (http://www.ge.ubuntuforums.org/showthread.php?t=1571102) where they are having the same issues.



I wonder if it is relevant to this (https://lists.ubuntu.com/archives/ubuntu-devel/2010-April/030673.html).

Here is an article (http://techie-buzz.com/foss/ubuntu-10-04-lucid-lynx-hit-by-major-memory-leak-problem.html) I found on the topic.

Any information on how to fix this or how to roll back the most recent patches would be great!
