Help very desperate.... We have a Zope site running: Zope version: Zope 2.0.1 (source release, python 1.5.1, linux2) (also happens on a seperate box running Zope 2.1.6) Python version: 1.5.2 (#6, Sep 22 1999, 10:32:58) [GCC 2.8.1] System Platform: sunos5, Ultra-2 It seems that if a user hits a page that either does an intense database query or iterates over a large number of items, all other users are prevented from accessing any page....! This problem may to be related to the dtml-in but we are not sure. For example suppose user A hits the following page (before user B hits his page): <!--#var standard_html_header--> <dtml-in "_.range(999)"> <dtml-var "_['sequence-item']"> <dtml-in "_.range(999)"> <dtml-var "_['sequence-item']"> </dtml-in> </dtml-in> <!--#var standard_html_footer--> And User B tries to access this page: <html><head> </head> <body> This is test </body> </html> User B is prevented from accessing his page until User A's page returns. Please help ASAP Dan
