CPU overload on MS SQL 2005

SQL database is causing a CPU overload by locking CPU resources with query

create table #tmpDBCCinputbuffer ([Event Type] nvarchar(512),
[Parameters] int, [Event Info] nvarchar(512))
insert into #tmpDBCCinputbuffer exec ('DBCC INPUTBUFFER(83)')
select [Event Info] from #tmpDBCCinputbuffer

What is possible reason and solution for this problem?
Avatar of udayshankar

how many records are we talking about here?? roughly..

select clount([event info]) from # tmpDBCCinputbuffer??

is the updates into that talble from the source and your insert happening at the same time??
He creates the temp table and then the insert would do a single record.  Two questions:

1. What is spid 83?
2. What are you looking at that makes you think it is this sql that clobbers the server?
Run these lines one after another. The insert into is probably causing the load, but just in case.
So before you run this everything is fine and as soon as you run it it spikes the CPU?

MS SQL Server 2005 Standart  Edition with SP1.
Windows 2003 Server Standart R2
4 x 3.0Ghz CPU`s, 3Gb RAM

The problem is that tihs query is internal sql server process when log cash must be flushed on replication. The process not hungs up but it runs slowly and locks other queries and log flush wait time starts to grow on realtime. This is not happening everytime but suddenly on one of sql server replications on normal daily work load.
