Something is definitely not right with your system.  It really shouldn't
be that painful.

The missing package database entries can usually be recovered by forcing
a reinstall of the package over what is already on disk, but if
everything is working properly, I wouldn't worry too much about the
contents of /var/db/pkg.

I'm thinking that having the registry of installed ports in a completely
separate partition or ZFS (ie /var) to where the ports are installed
(/usr/local) is not ideal, especially when using snapshots to provide a
roll-back capability.  /usr/local/var/db/pkg perhaps?

Yes -- you could well be having hardware problems.  Try a few passes of
memtest86.  It's in ports, but it's a standalone application you boot
into so concepts of compatibility with particular OSes is irrelevant.

Also do the usual stuff removing any dust or fluff that may be clogging
up the ventilation holes or heatsinks, check that you've still got a
good thermal contact between the heatsink and CPU (replace thermal
compound if necessary).  Also make sure your power supply is up to the
job.  They can fade over time, or you may have added a peripheral too
far.  [Although generally if anything here was wrong, you'ld see the
machine crashing and rebooting rather than it affecting use of the ports...]

	Cheers,
