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

[Allen]

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!!!
