Hi Guys,

I have an issue with one of my nodes on a sql 2008 r2 cluster (10.50.4000).

On one of my nodes when I run profiler I get corrupted/messed up sql and the application recieves an error that there is an invalid object (basically because the sql is messed up).

When we fail over to the other node everything seems fine.

I am unsure what other information may be helpful to diagnose this problem - but if someone can give me some pointers on what to look for here that would be appreciated!

thanks

Where are the invalid T-SQL statements coming from? Unless it is some internal queries that the DB engine is doing I would imagine that all T-SQL would be coming from a client issuing T-SQL statements to the db.

Are any errors listed in the SQL Server, Windows Event or cluster logs?

no its coming from a third party application.

The application is returning object not found error along with what the query is supposed to be. The same query gets shown in profiler with some malformities.

And when SQL is on the other cluster node the query does not come through malformed?
