The error:
Random queries begin to fail and return this error "Got error 127 from table handler"

The cause:
This error usually means that MySQL's datafiles have been corrupted and the table handler can nolonger read them properly. Wether or not the error occurs depends on wether or not mysql tried to read that part of the file that is corrupted.

The solution:
Usually this can only be solved by repairing the datafiles manually.
How this is done is explained in the MySQL manual: 4.4.6.9 - how to repair tables
