[j-nsp] M20 buffer fault?

[Gordon Smith]

Hi all,

Just came across an odd problem with one of our M20's - I've got JUNOS
7.4 on there for testing at the moment. I noticed that the router had
become unresponsive, and when I went and had a look at it, both RE's
were online as masters.

In the logs, this is what was occurring right up until I reset the box:

Oct 26 21:37:49  jcore2 /kernel: Out of mbuf clusters - adjust
NMBCLUSTERS or increase maxusers!
Oct 26 21:37:49  jcore2 /kernel: Out of mbufs (error count: 1)
Oct 26 21:37:49  jcore2 /kernel: Out of mbufs (error count: 1)
Oct 26 21:37:49  jcore2 /kernel: Out of mbuf clusters (error count: 1)
Oct 26 21:37:50  jcore2 /kernel: Out of mbufs (error count: 1) 


At the moment, the router is split into logicals (for vertical
aggregation), running BGP and IS-IS. Nothing really unusual. There are
still some unconfigured peers, but I wouldn't think that unconfigured
peers knocking on the door would cause resource exhaustion.

Anyone have any info on this? It's not a fault I've seen before...


Cheers,
Gordon
