After upgrading to SQL-server 2005 the following error message occures on a
random basis.  The SQL-server does not have any deadlock.
It worked perfect before the upgrade and no database changes were made after
the upgrade.
The serviced components are called from asp.net 2.0.

If anyone have experience similare errors please post your suggestions.
