Can we see what is at line 10 of your <PythonScript at
/siopen_r_net/util/pageInit> ?

Objet : [Zope] AttributeError: RESPONSE ?!

hi list,

this one has got me stumped; from the traceback:

Module ZPublisher.HTTPRequest, line 1220, in __getattr__

AttributeError: RESPONSE

AFAIK the REQUEST object should *always* have a RESPONSE attribute, right?


* this happens under moderate load in our somewhat involved data entry 

* load generated by apache benchmark at a concurrency level of 1-2 plus

* occurs at random, one out of 5 clicks maybe

* ZEO setup, zope 2.7.4, Python 2.3.5 (#2, Feb  9 2005, 00:38:15) [GCC 3.3.5

(Debian 1:3.3.5-8)] on linux2

under similar conditions i sometimes also get an "AttributeError: SESSION" which looks like somehow REQUEST is loosing its attributes? can that happen?

*any* thoughts greatly appreciated before i have to break out gdb and
myself for days in it :-/

 - peter.

ps.: somewhat abbreviated traceback below
