[nsp] Cat4000 Oddities

[Darren Smith]

Hi

 

I have an odd one for you...

 

Seems a few weeks ago when I was on holiday our core Cisco 4006 (has 1 x 6
port Gig-E & 1 x 48 port FE - ver 6.3.3) started putting random errors in
the logging buffer ->

 

%SYS-4-P2_WARN: 1/Blocked queue on gigaport 4, ( 19 : 894 )

%SYS-4-P2_WARN: 1/Blocked queue (rx) on ports 3/1 3/2 3/3 3/4 3/6 3/5 3/7
3/8

 

A few weeks on and now it's getting more and more frequent (i.e every 1.5
minutes ish)

 

Every now and again it also adds:

 

%SYS-4-P2_WARN: 1/Astro(3/1) - timeout is persisting    <- (Astro!?! Heh)

 

Anyway, Shortly after the 'timeout is persisting' it appears interfaces are
resetting but no real info is logged.

 

Suppliers are getting interface resets on the Gig-E ports and BGP is
flapping.

 

Ever seen this odd behaviour before?

 

Any thoughts would be appreciated

 

Best Regards

PS. Disabling interfaces at random at midnight - fun ;-)
