The following is the last two rows in errorlog. 2009-05-27 15:43:51.32 spid140 Invalid buffer received from client.. 2009-05-28 01:05:40.90 spid2 SQL Server is terminating due to 'stop' request from Service Control Manager. In that time integrity check was working in two databases (the job begin at 1:00). Plenty of space, etc., W3k sp1, sql 2000 sp4 last fix. After stop, the two databases was settings to suspect (after sql service up at 9:00). The only way to get those on line was restore. My question is: What are the reasons for "sql server is terminating....". Manual is one of them. Is there any other?
