We're running the latest released Webware, Linux (RH 7.3), Python 2.3.2,
Apache 1.3.x, mod_webkit adapter, and we're using the File session store.
We're seeing an increased number of KeyError tracebacks, where the "key" is
the session key. Interestingly, we just got two tracebacks within a couple
seconds; the first complained about the missing key, but the second (two
seconds later) had the key. These were from a user who had been logged in
for a while.
I'd be grateful for any ideas about what's going on, suggestions on where to
look, etc.
One more bit of important information: We have load-balanced Apache servers,
and the session files are stored on an NFS-mounted directory. We're doing
this precisely because of the load-balancing, but if it's causing the
problem, we'll have to find another way. In the case below, the first
traceback was from one server, and the second was from the second.
First traceback (14:17:38Z):
/home/adc/adc/wwwroot/ADCContext/GraphicalWX.py
Traceback (most recent call last):
File "WebKit/Application.py", line 395, in dispatchRequest
File "WebKit/Application.py", line 494, in isSessionIdProblematic
File "WebKit/HTTPRequest.py", line 222, in session
File "WebKit/Transaction.py", line 67, in session
def getSessionID(self):
File "WebKit/Application.py", line 963, in createSessionForTransaction
File "WebKit/Application.py", line 789, in session
File "WebKit/SessionFileStore.py", line 55, in __getitem__
KeyError: '20040529141722-e0962267bdec1bed52cab612f612aba1'
But the second (probably generated by reloading the Error page) has the
session key just fine (I've deleted most of the traceback). It was generated
at 14:17:40Z:
/home/adc/adc/wwwroot/ADCContext/ErrorPage.py
