Batch Delete - Timeout

Every time I try to do a batch delete from the admin section get a timeout error.  After I run it two of three times it will eventually finish without an error.

What's the error?

If it's a session timeout, you can add a session.timout command to the script to increase the number of minutes a session lives - if your host doesn't have an override in place.

For a DB timeout, the host needs to increase the amount of time allowed to run an mssql/myssql query on the db server.

If it's a timeout connecting to the db, either your host needs to tune their network or you need to run in off-peak hours.
