Hi dane
I think what really fixed it were the lines I added to the directives
WSGIDaemonProcess wms user=www-data group=www-data processes=10
threads=1
And
WSGIProcessgroup wms
Right, because otherwise the default is likely threads > 1.
From the 'WSGIDaemonProcess' section at:
http://code.google.com/p/modwsgi/wiki/ConfigurationDirectives
threads=num
Defines the number of threads to be created to handle requests in each
daemon process within the process group.
If this option is not defined then the default will be to create 15
threads in each daemon process within the process group.
Although to be exact, the impact of changing the defaults by
explicitly using the WSGIDaemonProcess line will differ depending on
whether the Apache server is 'Pre-fork' or 'Worker'. By setting it you
essentially are able to control the behavior of processes and threads
such that the type of Apache deployment does not have an impact. For a
detailed explanation of this see:
http://code.google.com/p/modwsgi/wiki/ProcessesAndThreading
Take home:
1) ALWAYS use the setting 'WSGIDaemonProcess' and until #3 is solved
always set threads=1 while processes=<anything you'd like>
2) Mod_wsgi is incredibly cool when used right.
3) Some threading issue or bug in lxml or the ogcserver requires some
attention because it should be able to be used in a multi-threaded mode
When I set the processes to 1, it worked. So I decided to try for
10, and it still worked
I installed python-lxml using apt-get.
great.
