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
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:839 errors:0 dropped:0 overruns:0 frame:0
          TX packets:839 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:78326 (76.4 Kb)  TX bytes:78326 (76.4 Kb)
Has anybody observed such behavior?

Any ideas how to fix this?

TIA,
Gellert
