__alloc_pages: errors resolved? [wa Re: __alloc_pages: 2-order allocation failed]

[Mike Edwards <sauron-debian-sparc@psychology.rutgers.edu>]

I've abandoned the Debian 2.4 kernels in favor of vanilla 2.4.30, and
this problem has yet to crop up.

 11:03:06 up 9 days, 18:42, 13 users,  load average: 0.47, 0.17, 0.14

Working on 10 days uptime, and no complaints.  The SMTP server has yet
to stop responding, too.

David?  I know you thought this problem was with SA (and I agree that
there may be an issue with how SA does things), but as I thought, there
seems to be a larger problem with the kernel, unless memory allocation
errors are commonplace (strangely, this is the ONLY box I've ever seen
this occur on).  Care to acknowledge this?

Judging from Ansgar's post, 2.4.30 doesn't necessarily fix things
(though it seems to be working in my case - there does seem to have
been a few modifications to kmem_cache_grow and related functions
between Debian's 2.4.27 and vanilla 2.4.30).  Instead of ignoring the
issue, can you please look into it?

Thank you.
