higher load after upgrade to sles11 sp2

SUSE Linux Enterprise Server SLES Configure-Administer
1

Hi,
recently I upgraded a few sles11 sp1 servers to sp2. Everything went fine, but after the upgrade the load got higher on the servers.

Linux nagios 3.0.34-0.7-xen #1 SMP Tue Jun 19 09:56:30 UTC 2012 (fbfc70c) x86_64 x86_64 x86_64 GNU/Linux

This server has also a lot of dropped packets since the upgrade.

[CODE]nagios:/etc/nagios/objects # ifconfig
eth0 Link encap:Ethernet HWaddr 00:16:3E:41:95:DB
inet addr:10.9.33.140 Bcast:10.9.47.255 Mask:255.255.240.0

RX bytes:78326 (76.4 Kb) TX bytes:78326 (76.4 Kb)[/CODE]

Has anybody observed such behavior?

Any ideas how to fix this?

TIA,
Gellert

Hi
Have you seen this thread about dropped packets?
http://forums.suse.com/showthread.php?t=1320

Have you looked in /var/log, is a log file increasing, also run top to
see what’s running. Maybe vmstat or iostat to see if it’s disk related.

Hi,
thank you for the forum thread, i will monitor it. It is good to see, that i am not alone with this problem.
There is nothing in the logs, vmstat, iostat, top is normal. Nothing eats up cpu, memory or disk.
