4500x VSS config-register not synced

[apache_le]

I have 2 4500x switches operate in VSS.  The current config-register value is 0x2101 and I want to change it to 0x2102.  I changed it on the primary, did a  write mem and the primary chassis says it will be 0x2012 at the next reboot.  However, the config-reigster on the standby chassis still says 0x2101.  I thought the config will be synced but it's not. How do I have the standby chassis to have 0x2102 at the next reboot?

Can you try using the "session switch 2" command?

you can't configure on standby

Have you solved this problem? What's the resolution for this? We are about to reload both core switches and I'm confused if this will not be an issue?
Active: 0x2102 on next reload
Standby: 0x2101

What is the resolution for this problem?

It seems that the issue is with the output of the command:

sw#show bootvar
BOOT variable = bootflash:cat4500e-universalk9.SPA.03.11.05.E.152-7.E5.bin,1;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x2101 (will be 0x2102 at next reload)

Standby BOOT variable = bootflash:cat4500e-universalk9.SPA.03.11.05.E.152-7.E5.bin,1;
Standby CONFIG_FILE variable does not exist
Standby BOOTLDR variable does not exist
Standby Configuration register is 0x2101
Standby Configuration register is 0x2101
sw#

If you connect to the standby switch you can see that the register will change on next reboot:

sw#session module 1
Connecting to standby virtual console
Type "exit" or "quit" to end this session

sw-standby-console#show bootvar

BOOT variable = bootflash:cat4500e-universalk9.SPA.03.11.05.E.152-7.E5.bin,1;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x2101 (will be 0x2102 at next reload)

I also encountered this exact problem with 4500x switch model. Me and TAC decided to reboot the entire chassis and it booted normally to the new image 03.11.04.E
