Zope has been dying silently with the following configuration: Zope version: Zope 2.2.1 (binary release, python 1.5.2, linux2-x86) Python version: 1.5.2 (#10, Dec 6 1999, 12:16:27) [GCC 2.7.2.3] System Platform: linux2 ZOracleDA-2.2.0b1 Oracle 8i (8.1.6.1) Not being able to figure out what the problem was, I replicated the site on WinNT zope. Crashes repeated there too with NT popping up a dialog box telling that python.exe could not read some memory location. I tracked the problem down to a query that returned ROWID's from an Oracle table. Upon rewriting the query to eliminate the need for ROWID's, crashes went away and Zope has been up since. Anybody had a similar experience? Is it a problem with DCOracle included? Ayhan
