Hello,
I am testing the deployment of an application under:
Ubuntu: 10.04
TG2.2.0
Apache/2.2.14 (Ubuntu) mod_wsgi/2.8
Intermittently (say every 48 hours of so), the app crashes with the
following:
[Sun Dec 09 14:37:49 2012] [error] mod_wsgi (pid=23383): Target WSGI script

The problem seems similar to that in
http://osdir.com/ml/turbogears/2011-03/msg00052.html, but I did install the
VE with --no-site-packages and within my environment, I can run python -c
'from transaction import interfaces' w/o an error. It does not seem to be
a problem with a missing package. transaction-1.3.0 seems to be the
current requirement (I easy_installed it just to be sure and that was the
version present). I ad the same problem with the same app with TG2.0
deployment and was hoping the upgrade to TG2.2 would fix it, but so far no
luck.
I have a cron job that restarts apache every night and that seems to work
OK, but looking for the cause of the problem.
Any ideas?
Thanks,
Shane
