Microsoft C++ exception: SqlException at memory location

1，查看CPU占用量最高的会话及SQL语句

select  spid,cmd,cpu,physical_io,memusage,
(select  top  1  [text]  from  ::fn_get_sql(sql_handle))  sql_text
from  master…sysprocesses  order  by  cpu  desc,physical_io  desc

2，查看缓存重用次数少，内存占用大的SQL语句

SELECT  TOP  100  usecounts,  objtype,  p.size_in_bytes,[sql].[text] 
FROM  sys.dm_exec_cached_plans  p  OUTER  APPLY  sys.dm_exec_sql_text  (p.plan_handle)  sql 
ORDER  BY  usecounts,p.size_in_bytes    desc
