You probably DO want the adaptor logging on per /System/Library/WebObjects/Adaptors/Apache2.2/apache.conf
# Note: To enable logging, touch '/tmp/logWebObjects' as the administrator user (usually root). # # The following line is the default: WebObjectsLog /Library/WebObjects/Logs/WebObjects.log Debug Also, you can inspect some of the adaptor's state by going to: http://yourhost/cgi-bin/WebObjects/WOAdaptorInfo?yourPasswordInTheApacheConfFileMentionedAbove In particular look at the "dead timeout" on that page.
