SLES 10 SP2 possible kernel problem, / slowly filling up
Hello Guys
I first though about posting this to emergency but cause I fixed my issue with an reboot its not as important, more is important to me what caused this situation
Some facts:
OS: SLES 10 x64 SP2 (Virtualized Vmware ESX 3.5) / vmware tools status OK
Soft: Oracle10g
LVM partitioning
/boot
/
/usr
/tmp
/var
/oracle
have separate. LV's
I usually have ocupated about 120MB from 2GB , means about 1.8GB free space
today I noticed that for some reason I got only only 100 MB of free (df -h)
still when U used du -shx / - shows Im using 130 MB, wth?
I would have all the the world for troubleshooting but the usage shown with df -h / was showing the the free space is decreasing about 20 MB/1 hour.
I found no obvious errors in /var/log
There was only one BIG file I found in the /proc folder called kcore, size = 4TB, read on many sites as on this is virtual file representing the memory. I compared the /proc/kcore file on other 10 SLES server but the kcore file was 0 size.
I read that the /proc/kcore is absolutely not consuming any space, at all, so now comes the question what was comsung slowly the space on root partitions?
After I rebootet the system all was as expected, 2 GB total space, 190 MB user, and 1.8 GB free
I monitored the space changes for about 2 Hours and it remains the same.
One more hint
After executing service ntpd stop i got an error with umounting, /var/lib/ntp/proc
I checked lsof also on /proc/kcore, but nothing was using this file.
I would appreciate any help or tips what to check, or some hints what to look for in the logs.
Thank you in advance

Can anyone give me a little clue on why the hard drive cache read timings on sles 9 is better then sles 11? The same hardware was used in both test. I even deleted the ata_generic module from initrd.
The speed difference is 10MB vs 5 MB

acctcms
acctcms(1M) System Administration Commands acctcms(1M)
NAME
acctcms - command summary from process accounting records
SYNOPSIS
/usr/lib/acct/acctcms [-a [-o] [-p]] [-c] [-j] [-n] [-s]
[-t] filename...
DESCRIPTION
acctcms reads one or more filenames, normally in the form described in acct.h(3HEAD). It adds all records for processes that executed iden-
tically named commands, sorts them, and writes them to the standard output, normally using an internal summary format.
OPTIONS
-a Print output in ASCII rather than in the internal summary format. The output includes command name, number of times executed, total
kcore-minutes, total CPU minutes, total real minutes, mean size (in K), mean CPU minutes per invocation, "hog factor," characters
transferred, and blocks read and written, as in acctcom(1). Output is normally sorted by total kcore-minutes.
Use the following options only with the -a option:
-o Output a (non-prime) offshift-time-only command summary.
-p Output a prime-time-only command summary.
When -o and -p are used together, a combination prime-time and non-prime-time report is produced. All the output summaries are total
usage except number of times executed, CPU minutes, and real minutes, which are split into prime and non-prime.
-c Sort by total CPU time, rather than total kcore-minutes.
-j Combine all commands invoked only once under "***other".
-n Sort by number of command invocations.
-s Any file names encountered hereafter are already in internal summary format.
-t Process all records as total accounting records. The default internal summary format splits each field into prime and non-prime-time
parts. This option combines the prime and non-prime time parts into a single field that is the total of both, and provides upward
compatibility with old style acctcms internal summary format records.
EXAMPLES
Example 1 Using the acctcms command.
A typical sequence for performing daily command accounting and for maintaining a running total is:
example% acctcms filename ... > today
example% cp total previoustotal
example% acctcms -s today previoustotal > total
example% acctcms -a -s today

NOTES
Unpredictable output results if -t is used on new style internal summary format files, or if it is not used with old style internal summary
format files.
