[j-nsp] Crashing rpd on 8.5R4.3 on Backup RE (M20)

[Callum Barr]

Yer... I'd log it with JTAC in that case...

We had a similar issue when we had 64meg RAM on our SSB's.  RPD would come up - sync with the backup RE, BGP would come up, that it would get to a certain number of routes and crash.  Can confirm NSR works sweet on an M20 running JUNOS 9.1R2.10 tho :P

Oh sorry.. You meant SSB.. We have 128MB on them (heap utilization is ~35%) ... So it's enough... 

That's what the gdb says on the core-file:

(gdb) bt
#0  0x081bbbff in aspath_path_reinit ()
#1  0x0820cf91 in bgp_recv_v4_message ()
#2  0x0820d11c in bgp_reinit_rt ()
#3  0x0821194e in bgp_rt_send_init_nlri ()
#4  0x08212d80 in bgp_rti_peer_terminate ()
#5  0x08212e9e in bgp_rti_peer_terminate ()
#6  0x080e8736 in task_job_bg_dispatch ()
#7  0x080e0120 in main ()

Maybe there's some "illegal" aspath that's causing rpd to crash.

Hi,

How much RAM do you have on your SSB's?  I don’t think it is the RE RAM that is causing the problem.

Hi,

We have RE-2.0 with 768MB.. I run a "top" while testing this issue and the ram is not fully used (there's ~70MB of free memory) ... I spent now several days with debugging this issue but didnt come to an end.. The backup RE is syncing with the primary RE .. And after it finished (the CPU usage of rpd goes down) the rpd crashes ... 

I put a gdb on the core-file(s) and it's always a aspath_path_reinit that's causing the core dump.

Best regards,

 Joerg

Just out of Interest - how much RAM do you have in your SSB's?  I had the same problem trying to run NSR on our M20's with not enough RAM. 

Cheers,
Callum

I agree with Jon. It would be better if you can open this case to Jtac.
They can help you identify and found which problem on your
router, especially when the problem had occurred many times or you can
reproduce it on your router.

IMHO, sounds like its a bug.
Btw, do you have multicast and aggregate interface configuration?

Regards,
Nugroho
