hi everyone,
I maintain a couple of linux servers in an academic environment.
Having upgraded most of them to 2.6.10-ac12, one of them showed a linear
growth of used memory over the last 7 days, after the first 2.6.10-ac12
boot. It came to a point that it started swapping and the swap usage too
started to grow linearly.
Most of the userspace memory was occupied by postfix and spamassassin
processes, which after killed didn't stop the memory growth, so I'm left
with the feeling of a kernel memory leak.
This is mostly an e-mail server:
* smtp for about 300 hosts (postfix)
* 6 local e-mail accounts for in-house administrators
** spamassassin for the local accounts
** courier-imap-ssl for the local accounts
Running on a 2.0GHz P4 with 512Mb of ram.
kernel version is 2.6.10-ac12 [1]
kernel config: [2]
Since this is a production machine, I can't test it very thouroughly
(lots of reboots, etc), but I'd like to know more about this.
I had to reboot it, so it's all normal now.
If the behavior maintains, how can I infer if there is really a memory
leak? What kind of tests could I perform?
best regards,
pedro venda.

cat /proc/slabinfo please. I am also seeing similar symptoms (although that is
with 2.6.11-rc4 there is a possibility of a common bug) here and I seem to
have linearly growing size-64 in slabinfo.

there isn't much to look at right now...

If you're using md, you need this patch to fix a bio leak:

thanks.
has this patch been included in the recent rc's?
and howcome the other servers work normally [all with md]? at least so far the
memory usages aren't concerning, although the linear increase is starting to
show. perhaps the [different] apps running on them don't expose the leak as well
the one that broke today... is that reasonable?

correction: after looking at /proc/slabinfo, the counters around the bio lines
are 10-100 times bigger than all the other, so their also leaking.
I read some discussion on this list around this issue and people were not
positive the leak came from md...
any comments?
regards.

I had the same with swap being eaten especially by perl apps like qmail-scanner

There has been discussion in another thread about a leak related to
network activity. You might find more information there, subject
contains "NOT BIO" if it helps.

hi
I've read the leak thread above possibly about this bug... AFAI read, there isn't
really a conclusion about this leak, right?
here goes the /proc/slabinfo for 2 days uptime:

You have bio leak. Similar one was fixed in -rc4.
Did you already try using the md fix
http://linux.bkbits.net:8080/linux-2.6/diffs/drivers/md/md.c@1.234
And
http://www.kernel.org/diff/diffview.cgi?file=%2Fpub%2Flinux%2Fkernel%2Fv2.6%2Fpatch-2.6.10.bz2;z=4918
?
If not, is it possible for you to either port these fixes to -ac12 or use -rc4
and then report slabinfo after couple of days?
