[nsp] vip crash 12.2T and 12.2S

[Otto Kreiter]

Hi,

We try to run on our 7513 with 2 vip2-40 and one vip4-80 the 12.2(14)S ios 
but after several normal functional hour, and no abnormal traffic 
condition, it's crashed.

The problem is that most ios from 12.2(4)T and higher it's crash in the same 
way.

Logs contain:

Feb  4 09:06:09.453: %MDS-2-LC_FAILED_IPC_ACK: RP failed in getting Ack 
for IPC message of size 140 to LC in slot 0 with sequence 22, error = t
Feb  4 09:06:10.565: %IPC_RSP_CBUS-3-NOBUF: No more IPC memd buffers to 
transmit IPC message
Feb  4 09:06:24.461: %MDS-2-LC_FAILED_IPC_ACK: RP failed in getting Ack 
for IPC message of size 116 to LC in slot 0 with sequence 22, error = t

I see several vip restart. Restarting the router cannot return 
to "normal" function, like after the upgrade for some hours.

The only one ios wich is working fine is the 12.2(2)T.

Anybody experienced the same problem ?
Can bee the ipv6 dcef ?

Thanks,
Otto
