For the past 2 months on my sql server 2005 Active/passive 64 bit cluster I have had the server buried at least once every week but system processes related to this command
WAITFOR(RECEIVE conversation_handle, service_contract_name, message_type_name, message_body
FROM ExternalMailQueue INTO @msgs), TIMEOUT @rec_timeout
This table usually had only a few records, but this command still buries the server. Anyone seen anything like this before?
