problem load-average with kernel 2.4.18-19.7.x

[Jérôme Bolliet]

Hi,

We are using redhat 7.3 on Compaq DL360 2 processors with kernel 2.4.18-10smp without problem to make POP3 server, with Courier IMAP 1.6.2 and NetApp Filer F760 as NFS server.

We have upgrade one server with latest kernel without changing parameter. And the load average are high.

Servers are the same. Tuning are the same. We have ~100 connections on each server.

Top give us these information:

2.4.18-10:

4:51pm up 2:49, 1 user, load average: 1.02, 1.14, 1.08
113 processes: 109 sleeping, 4 running, 0 zombie, 0 stopped
CPU0 states: 5.1% user, 4.3% system, 0.1% nice, 89.3% idle
CPU1 states: 4.1% user, 6.4% system, 0.0% nice, 88.3% idle
Mem: 2065192K av, 717504K used, 1347688K free, 0K shrd, 77308K buff
Swap: 2097112K av, 0K used, 2097112K free 502364K cached

2.4.18-19.7.x

4:51pm up 2 days, 2:00, 1 user, load average: 3.77, 3.07, 4.76
107 processes: 106 sleeping, 1 running, 0 zombie, 0 stopped
CPU0 states: 5.4% user, 7.0% system, 0.0% nice, 86.4% idle
CPU1 states: 5.3% user, 8.0% system, 0.0% nice, 86.0% idle
Mem: 2064880K av, 2047500K used, 17380K free, 0K shrd, 87404K buff
Swap: 2097112K av, 0K used, 2097112K free 1782876K cached

We can see that the load is 3 time higher and the memory is heavy used on the 19.7.x kernel.

There is no error message
Any idea ???

Thanks
Best regards
