Don&#39;t know about this specific problem, but we just ran into something similar -- no upgrades, no changes, but Catalyst suddenly stopped loading (DBIx::Class::Schema::connection(): No arguments to load_classes). Wound up having to cpanm a bunch of upgrades by hand before it started working again.<div>
<br></div><div>So apparently our system either is configured for occasional cron-based upgrades and we managed to wind up in an unstable state as a result (still looking into this)... or black hats were involved.</div><div>

 I&#39;ve been looking and I can&#39;t seem to figure out what&#39;s going on.<br>

I suspect that it was an underlying Perl module that somehow blew up, but I&#39;m not sure.<br>
