Hello.
      We are faced with a similar problem.
      We have a lot ippa crash on seos 11.x, using the pppoe + enhanced
      nat. (se600 with 10ge-4-port linecards)
      On SEOS 12.1.1.2 was only 1 eppa crash (after 1 month uptime).
      On SEOS 12.1.1.4p1 aaad crashed after 5 days of work.
      Found a company that uses non dhcp clips + enhanced nat, they have
      ippa crash began after the nat logging enabling.
      You are using the enhanced nat? Nat logging?
