Take a look in the data directory for a .err file. This error log
will almost certainly contain the reason why Mysql failed to load and
will make fixing it much easier.

I wondered if any movement has been made to determine the cause of the
following bugs that I have come across using Mysql 4.0.1.

datasets aren't even that large and when there is bags of disk space.
2) Under FreeBSD
