[Catalyst] Suddenly Failing with Moose and MOP Errors

Sun, 30 Jan 2011 17:36:22 -0800

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.
