Mirrored port locked up firewall

Can anyone help? I have a major problem....
I have a Catalyst 1900 plugged into my Cisco PIX Firewall. I plugged a SurfControl server into this 1900 switch. I mirrored the port that goes to the firewall to the port that SurfControl is plugged into and it totally locked up the firewall. I reboot, etc and can no longer get through the firewall. I had a spare firewall so I plugged that in. Not thinking the mirrored port caused the problem I mirrored again and did the same thing to this firewall. Anyone have any idea where I can go from here? I've totally wiped out the config and reloaded it to no avail.
Thanks,
Craig
 
HI.

Maybe something is wrong with the switch configuration.
What is the pix device (5??) and OS version?
How are pix interfaces configured (auto,10baset,...)?
What NIC does the SurfControl have and how is it configured?
How are the switch ports configured(auto,10/100,half/full)?
Maybe port mirroring isn't working well with a mix of different port speeds.

Instead of port mirroring, try to connect a simple HUB to the switch, and both the Pix and SurfControl to the HUB.
Does it work better now?

Bye
