CARP hang in back up mode, can't get out of it

[timld]

I have tried upgrading one of our FW recently and while asking the FW to back up it stayed in back up mode and is now hanging and becoming unstable. can any one help ? thanks

What version was it upgraded from / to?

Is this unit usually your primary or secondary?

What exactly do you mean by "hanging and becoming unstable"? Is it access to the GUI that fails, or network connectivity, or what other symptoms?

Anything noteworthy in the system log?

Thanks for your reply, this one is my secondary.
