Not sure if this helps...

I executed the following command.  the pid 45937 was the process id that 
was in use when I did a ps auxw and searched for the portal-cert.pem file 
(or something like that)... so I know that was the correct process.

The first two "PIOCCONT: Invalid argument" were when I went to 
authenticate on my Firefox machine.  Worked fine.  Then I accessed with my 
IE machine, and thats what the rest of the messages are from.  Then the 
process died and so the truss died.  See the output of /var/crashlog at 
the bottom of this email.

$ truss -o /var/crashlog -p 45937
