4.3.2.BASE

Description (partial) 

Symptom:
A frequent dhcpd crash may be observed on a Cisco CRS and XR12k with IOS-XR 4.3.x and 5.1.1.


Conditions:
Whenever DHCP tries to send out a packet towards the access side, it  may assert a dhcpd crash.
The probability of DHCP sending packet depends on the packet reception and configuration.
If the device is supposed to be a DHCP relay/proxy, then crash happens very often as the incoming DHCP packets rate will be high.
