Qualitatively speaking, about 50+ lines of text. More data as we get more
reproduction cases.

Doesn't seem to be so far.

New-style. The URL is not accessible, as it is an intranet wiki with
confidential information. :(

Trigger the table bug? I will post a page to the master phpwiki.

No, but that Apache process goes bonkers, consuming huge amounts of CPU. PHP
terminates it after 30 seconds, giving up.

myisamchk succeeds on the .MYI files.

The partition has used 1.5GB and has 1.8GB free, which means it is 43% used.

Cool.

I will continue trying to reproduce this issue in a consistent fashion to
see what is breaking.
