[Catalyst] Suddenly Failing with Moose and MOP Errors

All of a sudden my  application stopped working and started spewing 
these errors.   This same code has been running for many days, then 
kblam!  Suddenly died.

  I've been looking and I can't seem to figure out what's going on.

I suspect that it was an underlying Perl module that somehow blew up, 
but I'm not sure.

Can anyone see anything in here that indicates what the problem is?

Thanks.
