[c-nsp] ASR920 - Any "outstanding" TAC cases people are working through?

[CiscoNSP List]

Hi Everyone,


Just reading through all the recent threads, and as we are about to deploy a number of these boxes in production, wanted to be 100% on any potential issues we may face (couple of recent posts, mention ASR920, ISIS stopping working(And routing unexpectedly), and reboot "resolves" the issue(temporarily)...this was also an issue on the ME3600's (As reported by Mark Tinka), and a work-around provided, but no actual fix by Cisco (Even though the bug has been present for some years?)....not too sure if this is the case on the ASR920?  Nor if it is ISIS specific?


I am aware of the following, and have applied the relevant "recommended" IOS update:

bug ID CSCux91894<https://bst.cloudapps.cisco.com/bugsearch/bug/CSCux91894>, which causes a memory leak with the default configuration.
Problem Symptoms
A memory leak on the ASR 900 Series routers is seen under the iomd process and even when the node state is idle.
When executed, this command shows the increased memory leak under spa_xcvr_oir.
#show platform software memory iomd 0/0 brief
The increased memory leak might cause the router to crash and reboot multiple times.


Are there any others people are currently working through on these boxes?



Our ASR920's will be used as "PEs"...runninging MPLS/BGP/VRF/OSPF, and terminating cust tails.


Just a little hesitant to deploy them atm....when we originally deployed the ME3600's, we got hit with a number of rather nasty issues, so am a little gun shy given the ASR920 is the "replacement" for the ME3600, and is also a relatively new box..


Thanks in advance.
