C7606-s reboot during switchover

Greetings,

Sorry about my bad English.

 

Had a troulbe with c7606-s during switchover.

Model : CISCO 7606-S

OS : 12.2(33)SRE1

Configured Redundancy Mode = SSO

Operating Redundancy Mode = SSO

 

Last week, c7606 was experiencing a bug which was generating same msg( "### msg pending.......") continously.

Then, I found out that it was an OS bug and workaround was the following :

     1) Switchover

     2) Reload

     3) OS Upgrade

 

Since if I reload the router, it will cause some trouble to services during the reload time, therefore decided to do "switchover"

 

For what I know and experience,

In SSO mode, both the supervisor(Active & Standby) modueles aren't suppoed to reboot during switchover.

 * LET'S SAY

        ACTIVE = module 1

        Standby = module 2

 

##### Used Command #####

redundancy force-switchover

 

As soon as switchover began, module 1 went on a soft reboot.

After 4min, module 2 went on a soft reboot.

After thoese two reboots, Active and Standby modules changed.

 

##### Problems faced #####

   1) In SSO mode, is it normal for both modules to go on a soft reboot during

   2) Only used SSH(no telnet) but after switchover didn't have access to remote via SSH (connection refused)

   3) SSH was disabled after switchover

 

##### Questions #####

1) Is it normal for both modules to go on a soft reboot in SSO mode?

2) Why does SSH was disabled? Is it an os bug?
