Server load keep going up

Hi,

One of my managed RedHat Linux 7.3 server is an Intel P4 2.4GHz server. For the past one month plus it is running fine but after I have upgraded its kernel to the latest one from redhat network... the problem started about a few days after the upgrade. The problem is server not responding after a while for several times and according to the provider's tech... it is up but the load is very high. The server isn't loaded with many softwares and it uses less than 50GB bandwidth last month. By looking at the /var/log/messages, it shows part of the following:
Code: 
May 25 04:04:28 ns1 kernel:  <1>Unable to handle kernel paging request at virtual address 73646e89
May 25 04:04:28 ns1 kernel:  printing eip:
May 25 04:04:28 ns1 kernel: c0150b5a
May 25 04:04:28 ns1 kernel: *pde = 00000000
May 25 04:04:28 ns1 kernel: Oops: 0000
Anyone can tell me what does the following means?
May 25 04:04:28 ns1 kernel: <1>Unable to handle kernel paging request at virtual address 73646e89

Thanks.

Kindest regards,
Choon
