[c-nsp] 12.3.22 lawful intercept on 7206 - DHCP bug eats 2, 000+ customers

[Neal Rauhauser]

  I have a 7206 with NPE-G1, upgraded from 12.2.15T11 last night to 
12.3.22 lawful intercept and simultaneously taking from 256m to 1024m of 
memory.

  The system has BGP peers and a couple of thousand DSL customers 
attached (I know, I know, OS and memory upgrade are part of me splitting 
it for this customer).

  We watched 2,100 ARP entries appear for the ATM PVCs this morning and 
all seemed well but the onboard DHCP was sick. We do a 'show run' and 
it'll fail with a "try later" or it'll run but it takes several minutes 
to generate anything.

  We're on the phone with TAC now and we've got someone clueful but this 
is incredibly painful for the customer - anyone seen this thing before? 
Suggestions?
