Critical errors and critical warnings

[Belinda Frick]

Critical Errors are checked every 10 seconds.

This includes messages like Cable unplugged, Framer errors, or
being stopped for cardservers, the sweeper running out of disk
space, or a serious error in the archive process (one that isn't
part of the normal archive error-handling for disk space,
permissions, individual file copying errors, checksums, etc.).

Critical Warnings are checked every 10 minutes.

This includes things like disk space / file errors during archiving,
license overruns. It also includes things like the system finding
problems with disks.
