mysql crash windows aio cannot continue operation
<p>today my installation of mysql 5.5.20 wamp has been randomly crashing.</p>

<p>seems like it fails at 
InnoDB: File operation call: 'Windows aio'.
InnoDB: Cannot continue operation.</p>

<p>i have run <code>mysqlcheck -c  -u root -p --all-databases</code> ,  and everything turns up OK.</p>
