CheckQueryProcessorAlive: sqlexecdirect failed

Hi,
I have the following error in my sql error log.
2004-05-05 09:44:34.23 spid3 SQL Server is terminating
due to 'stop' request from Service Control Manager.
I have the following error in my cluster log just before
my entry into the sql error log. Could you let me know
what could be the cause? The server load was not high and
the system was not running any dbcc at that time.

regards,
bharathThe cluster service was unable to connect to SQL Server to verify that it
was running. There are numerous reasons why this could happen. I then
shutdown SQL Server and, I assume, failed it over to the other node or
restarted on the same node.
