We have an SSH session that is killing our core.  I've tried clearing VTY0 but I get an error message.   None of the searches I've done also shows a way to kill a PID on this core.   Reload is also not an option. CPU utilization for five seconds: 100...

Can this be a straight upgrade are are there steps that must be taken first to get us to 9.4(4)17. I've looked around but cannot find straight information regarding this. Thank you. Rick
