Hi, We are running an application on Zope that connects back to an MS SQL Server 2000 database (Using mxODBC). The app is written using ZPTs, Python scripts and ZSQL methods. For performance reasons we have put all our queries in stored procedures, often one stored procedure will be called (through a ZSQL method) to retreive the data for a page and another to save data from that page. We have a problem where some of our users get a blank page while trying to load up one of the screens in our app. This screen contains a list of employees and their hours worked per day and in total for a week. The stored procedure for this screen is a little slow (the sum calculations are done in the SQL), it takes about 2 seconds to run through the Query Analyser. When doing a 'View Source' we get just the basic HTML tags - DOCTYPE,HTML, HEAD, BODY with nothing inside of them. So far this problem has only affected users at remote (low bandwidth) sites. Any ideas what could be causing Zope to return a blank page like this? Any suggestions? Thanks Tim Edwards
