Description (partial)

Symptom:

CNR DHCP server exhibits poor performance and is dropping packets.

BAC CNR DHCP extensions are emitting the follow error message to the DHCP server log:

The DHCP log contains messages indicating the extension "preClientLookup" is failing causing packets to be dropped:

name/dhcp/1 Warning Extension 0 04575 A processing failure occurred when processing extension 'preClientLookup' when run for extension point 'pre-client-lookup' on DHCP Request 'R123456'.
name/dhcp/1 Info Server 0 04473 Extension 'preClientLookup' running at extension point 'pre-client-lookup' on DHCP request 'R123456' failed, which forced the packet to be dropped!

Conditions:

BAC 2.7(1.7) or 4.0(1.4) or earlier is being used with CNR 7.1.
The DHCP server host machine processor contains many cores.
