[Zope] How to find a lost database adapter connection method

Subject says it all! (well, sort of) 2003-10-14T10:11:36 PROBLEM(100) ZODB Could not import class 'Connection' from module 'Products.ZODBCDA.DA' This shows up in our eventlog.log off and on throughout the day on both our Zope clients connected to a ZEO server. We used to use ZODBCDA but stopped a LONG time ago. We think there may be an errant method hanging around with a bogus database connection in it. Is there a way to magically search for the text in the connection string of a ZSQL method?? Thanks!!! Allen
