Yes an oracle DB and i'm using an external session service to store and
retrieve
session data using the httplib.
What do the hung threads say
they're doing on the debug info panel?
for example:
Connections:
Fri Sep 12 10:28:09 2003 (11650.65s) ({'HTTP_ACCEPT_ENCODING':
'gzip,deflate,compress;q=0.9', 'SERVER_PORT': '', 'PATH_TRANSLATED':

I think using httplib to return session data is risk to put it mildly. I'd put
money on the fact that it's either that or your ORacle query that's hanging...

Well, yeah, the result of that would be helpful...

As far as i know the ZServer (Web server) talks to the ZPublisher (ORB) to get the Requested Object. But do they communicate via tcpip sockets or unix sockets? They communicate by Python Method call :) From 100km overhead it looks like that: ZServer gets a request, handles all the protocol specific stuff, and gives it to ZPublisher. ZPublisher than gets the application object it publishes and traverses the tree to find the right method to call. The application object is usually (in the Zope case) fetched from the ZODB.
