I've been fighting with this since I did a fresh install of BE15 on a clean install of WS2008. Deleting the catalogs bought me about 3 weeks with no ODBC errors. They're back again at a rate of about 2000/day. If it happens again the way it did last time, it will be up to 50000/day in a short time. Errors in event log are:
Access to catalog index (Catalog index database) failed.
Reason: [Microsoft][ODBC SQL Server Driver][SQL Server]An error occurred in the Microsoft .NET Framework while trying to load assembly id 65536. The server may be running out of resources, or the assembly may not be trusted with PERMISSION_SET = EXTERNAL_ACCESS o CCatRecordSet::Open
