UC560 backup to CCA failing with IOS error

Prior to doing a full upgrade of my UC560, I attempted to use CCA to do a backup of my configuration, voicemail, etc.  The process seems to get fairly far (backing up CUE), and then CCA informs me that the backup failed.

I was getting "%SYS-2-BADSHARE: Bad refcount in retparticle" errors, so I separately upgraded IOS on my UC560 (thinking this was perhaps an IOS error that had been corrected), but I'm still getting the errors.  Here's a sample of the errors I'm getting with uc500-advipservicesk9-mz.151-4.M4b :

I'm reluctant to go ahead with the rest of the upgrade without having a reliable backup.

Jim,

You may also want to check your default gateway. If you are not using the UC as your default-gateway then make sure that the gateway has routes to all VLAN's of the UC. I have seen this a number of times where the default-gateway usually a firewall does not have the routes. Even though you can ping from your pc or do a route add it will still fail. The easiest method is connecting direct and changing your gateway to the UC.

Thanks,

Chris (Dennis)

As you said -- upgrading would be a bad idea.

The first thing the update process in CCA does is create a backup -- if this fails, either the upgrade will hard fail then, or if it continues, your config/data will not be imported sucessfully after the upgrade.

There are some references to that error on google -- though for a different platform.

The fix mentioned is a reboot of the router... that would probably be a good place for you to start.

Hi Jim,

Do you have "ip virtual-reassembly in" under all your ip interfaces - Gig0/0, Vlan1 etc.?

If not please add it and provide feedback.

HTH,

Alex,

Yes, the config already has "ip virtual-reassembly in" for Gig0/0, Integrated-Service-Engine 0/0, vlan1, vlan90, vlan 100. Any other ideas?

Hello Jim,

I would start by reviewing the connection requirements document:

https://supportforums.cisco.com/docs/DOC-9779

This docs discusses basic network configuration that will be needed in order to take a backup of the UC.

Thanks,

Well, okay, I can (and will) review the connection requirements.  But are you saying that if I don't meet one of the connection requirements, an IOS internal memory management error will result? There shouldn't be anything I can do from a PC running CCA that results in a %SYS-2-BADSHARE error.

Hello Jim,

No, I'd just like to start out by verifying the basic connection requirements. The error code you are seeing general refers to issues with the packets getting fragmented. Are you taking the backup locally?

Thanks,

Yes, the PC running CCA is locally connected through a wireless connection to a Cisco Aironet 1142 access point (bridging) and SF300-48P switch. It's on the same subnet as the data subnet the UC560 is connected to.

Good call!  I neglected to consider the fact that our SA520 is doing the inter-VLAN routing, so it was routing packets to/from the CUE (VLAN 90).  I reconfigured my CCA PC to a static configuration with the UC560 as the default, and the backup succeeded with no %SYS-2-BADSHARE errors.

Good workaround, but hopefully there is a CDETS bug open for the error -- it should work with packet fragmentation as well.

Thanks!
