I was running into this all the time.
I actually had myisamchk running on a regular basis (live) via cron
which I think was actually causing the corruption.
By chance are you running myisamchk on the live tables?? I ran the
REPAIR TABLE... on each table, shut down mysql THEN ran myisamchk
again and my 127 errors seem o be gone (so far).
What OS are you running BTW?
