Hi All we encountered this issue on our node 2 of SQL cluster. the environment is : windows 2k3 EE, SQL 2k EE + SP4. the SQL cluster runs fine on node 1. but when it failover to node 2, we have SQL jobs failure and found some "SqlDumpExceptionHandler: Process 98 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.." in the log file. this SQL alert "Fatal Error in Resource" is triggered. the SQL server sometimes hung there and App couldn't access database at all. we compared the patches and didn't find anything different on both node. does anyone have same issue? we could't find the usefull info online. any suggestion would be great. thanks in advance.
