More information required.
Are you running your application in embedded mode of mod_wsgi or in
daemon mode? If in embedded mode, you did read about the problems with
SQLObject and multiprocess web servers in:
http://code.google.com/p/modwsgi/wiki/IntegrationWithTurboGears
If running in daemon mode, are you running it as Apache user, or did
you configure daemon process to run as you? Also, if in daemon mode,
how many processes did you set for the daemon process group. Like
above, if more than one and using multiprocess server, there can be
issues, although it shouldn't be what you are seeing.
Anyway, post what the mod_wsgi configuration you are using is from
your Apache configuration.
