We have several user Linux devices on a ws-c6509 switch running 12.2(18)SXF12a code. When this user reboots his machine the port goes into err-disable with the following error message generated;
May 12 21:21:59.202: %DHCP_SNOOPING-4-DHCP_SNOOPING_ERRDISABLE_WARNING: DHCP Snooping received 100 DHCP packets on interface Gi6/42
May 12 21:21:59.206: %DHCP_SNOOPING-4-DHCP_SNOOPING_RATE_LIMIT_EXCEEDED: The interface Gi6/42 is receiving more than the threshold set
May 12 21:21:59.199: %PM-SP-4-ERR_DISABLE: dhcp-rate-limit error detected on Gi6/42, putting Gi6/42 in err-disable state.
The ip address for this device is static. My question is how this device would be sending out dhcp service advertisements if it is using a static ip address.

You're probably running dhcp servers on the boxes. Check to see if you are:
ps ax | grep dhcpd
If you get anything back other than the grep command, then you're running dhcpd and you need to disable it. Setting the device as a static address doesn't disable the dhcp service.
HTH,
