>Description:
-------------
This morning we were unable to access our databases from our applications.
After a closed check in the mysql-server, I found out that all the
databases had disappear. A "show databases" returned only ONE DB named
"vi.recover" , Is the first time I see this DB in our server.

If I tryed to access this DB, "use vi.recover" I got an error 
ERROR 1102: Incorrect database name 'vi.recover'.

All the files from the different DB where still in the HD.
After a shutdown of the mysql-server, check of the DB and starting the
mysql-server again, all my DB where back and "vi.recover" disappear.

- We use iasam tables.
- Some of them are some GB big with some millions entries.
- This is the first time I see this happend with the server and I am
  very worried, because these DB are a central part of our system and must
  be running all the time.

If you need more info, just ask me about it.
In advance, thank you for your help.


>How-To-Repeat:
---------------
No idea. No errors log anywhere.

>Fix:
-----
The only way to get all the databases back is to shutdown the
mysql-server, run myisamchk in all the databases and start the
mysql-server again.
