Constant unrecognised queries

Hi,
I’m getting serveral unrecognised queries per second.

SELECT * FROM INFORMATION_SCHEMA.ROUTINES WHERE ROUTINE_SCHEMA=’’ AND ROUTINE_NAME=’’

I get these for different stored procedures and databases. I am using the .NET connector so I suppose it may be related to that. Any idea what these are?

There are others too:

Our web server is sending “SHOW VARIBLES”.

Sometimes we get “SHOW COLLATION” (or something similar).

Does anyone know what these are? Especially the INFORMATION_SCHEMA.ROUTINES one?

Thanks,
