Database Error: TABLE FULL (wp_options & wp_postmeta)

I’ve searched the Internet, the forums, and the bug reports for 3 days to try to find an answer but couldn’t.

Had a clean install of 2.3.0 with MySQL on a Windows Server.

Worked perfectly with the theme and all plugins for 2 weeks. Then suddenly this error occured. (about 100 posts are up)

Error: upon editing or publishing I get a Database Error that two Tables are Full

WordPress database error: [The table ‘wp_postmeta’ is full]
INSERT INTO wp_postmeta (…) VALUES (…)

WordPress database error: [The table ‘wp_options’ is full]
UPDATE wp_options SET option_value = ‘a:424:{i:1192930370;a:1:{s:8:\”do_pings\”;a:1:{s:32:\”40cd750bba9870f18aada2478b24840a\”;a:2: …lots of data here…’
WHERE option_name = ‘cron’

Actions Taken:

1. Deactivated all plugins – errors still there
2. Backed up the database, upgraded to 2.3.1 from 2.3.0, first deactivating all plugins – errors still there
3. Opened up the DB (have a dedicated server) using MySQL Administrator and looked at the schema. No table is even 50% capacity and the two tables in the error wp_postmeta and wp_options are at 144kb and 1.1MB respectively

The Table Types are InnoDB and I’m not sure if that would be an issue since the default size should be 2TB on a Windows server:

I wouldn’t think that a table could fill up after a blog is up for two weeks. The site itself is fine. These errors only occur when trying to write or edit a page or post.

The issue wouldn’t seem to be the theme or any plugin based on the tests I have done above, but who knows.

I’ve searched everywhere for an answer because I don’t like to waste anyone’s time. There does appear to be a lot of data in the ‘cron’ row of the [wp_options] table but I don’t know if that is normal.

Thank you for your professional help.
