Cisco ASR

Anyone using ASRs? We are demoing one to possibly upgrade our 7206s.
We are seeing what looks like a memory leak on the RP. Cisco is looking
at it and says they haven't seen it before. I am wondering if anyone
else has run across this. With the default 2G of memory the RP only had
about 1% free memory, and the router was rebooting every 5 days or so
when the RP ran out. We upgraded and now have about 60% free on the RP,
but I still see the used memory incrementing at a pretty steady rate.
We are running IOS-XE 12.2(33)XNF.

The router is currently not even routing traffic, just acting as a BGP
peer so it has one set of full tables. It seems to be a process on the
Linux OS side that has the leak as the IOS memory commands show
everything staying pretty static.

I am using a few 1002's and I am not seeing that issue. I will get you the
IOS train later.

Could a Google Op get in touch with me off-list please? I have a fairly
stupid situation....

using ASR1006 here, had 2 automatic reboots last friday which is not a
good sign.

System image file is
Last reload reason: Critical software exception, check

last thing i always see before boom,

May 21 07:27:11.752 XXX: %BGP-6-BIGCHUNK: Big chunk pool request (252)
for community. Replenishing with malloc

i am starting to feel ASR1000 series' software is not yet ready for
primetime, but there are newer software available, will try that first
and if it still fails, then i'll cancel all ASR1000 orders.

for a few days ago, i just tested the ASR1006, i tested it for 2 weeks and it never reboot itself.
  i was using IOS: asr1000rp2-adventerprisek9.BLD_V122_33_XNE_ASR_RLS5_THROTTLE_LATEST_20090926_060026.bin

i tested it for bgp propagation and pppoe. i think it enough good.

Re guys,

just to enforce the statement that the ASR is not really in the Kindergarten

rt uptime is 22 weeks, 1 day, 17 hours, 33 minutes

Let's move this specific crash/code question over to

Try the 12.2(33)XNF1 release.

If you would like to try and find the matching bug for what you are seeing before you upgrade email me offline with the crashinfo file and the full logs and I'll get someone to take a look at it with you.


I've been running two asr1002's in production now on XND2 and so far
(he knocks on wood) they've been stable. Very simple config on my end,
OSPF, BGP with full routes, all interfaces are fixed, IOW, no add on
SPAs. I can push well over 100k PPS on each interface and the boxes
are asleep. My NPE-Gx's would fall over at that rate. All in all, I've
been pleased with them. Now, if I could just jail break the ASR;s and
load JUNOS.... :wink:
