i tried bashing zope.1.10.3 running with apache 1.3.6 some by doing this: in index_html: <!--#var p--> <!--#var p--> <!--#var p--> ... <!--#var p--> (like 30 time or so) ------------------------ and in p <!--#var p2--> <!--#var p2--> <!--#var p2--> ... <!--#var p2--> (like 100 times) ------------------------ and in p2 asdfasdfasdf<BR> so, to me, that makes like requesting index_html would result in 30.000 lines of text. fine. but for several minutes, this is what was happening: 13694 apache -25 0 32M 30M run 14:39 92.48% 91.68% python ... the pcgi_publisher? i don't know, actually, but that's what i would assume. problem is, i did this: kill 13694 and now Zope won't start, so i cannot reproduce the error. all i get is this error message: <html> <head> <title>exceptions.ImportError</title> </head> <body> Sorry, a SERIOUS APPLICATION ERROR occurred.<p> <!-- Traceback (innermost last): File /disk/tools2/Zope-1.10.3/lib/python/ZPublisher/Publish.py, line 878, in publish_module File /disk/tools2/Zope-1.10.3/lib/python/ZPublisher/Publish.py, line 325, in publish File /disk/tools2/Zope-1.10.3/lib/python/ZPublisher/Publish.py, line 616, in get_module_info File /disk/tools2/Zope-1.10.3/lib/python/Main.py, line 93, in ?

ImportError: ('InstallError', 'No access file found - see INSTALL.txt') --> </body> </html> ... and that happens although that files is most definitely present. can anyone help? i'd really appreciate that. and one more question: when does Zope serialize incoming requests? what exactly will happen when i request an object that will result in a large and time-intensive sql query being send to an external relational database - will the orb stop accepting requests until that one request has been dealt with? why did Zope just block when i requested index_html as in the the example above? thanks ruben
