 Subject:  DHCP Client woes
 Date:  Sat, 26 Jan 2008 01:09:04 +0100
Hello,

In the system log I've noticed the following strange behavior of the
DHCP client on the WAN interface.
When I'm downloading (news-groups and file download from Microsoft) I
see a lot of DHCP renewals, more then one per minute. When I stop the
downloads DHCP renewals return to normal values.
I'm running m0n0wall 1.3B9 Generic-PC-CDROM on a Compaq Deskpro with a
400MHz Celeron, 384MB memory and 3Com nic's. 
I've added a partial log for information. The log starts during a
download until 22:43. Then the internet connection is only used for
browsing and email. At 00:48 downloading is started again.
During downloading the memory usage is 11% and processor utilization is
averaging around 10% (min 6% and max 30%).
I've seen this behavior with 1.3B8 as well. Don't remember if I've seen
this with earlier versions.

Any comments?

Regards,
MarcelK.
