Apache using 99% cpu, when web2py accessed using JQ-mobile - latest psycopyg2 used

[Nik]

I've posted the question on StackOverFlow too, but I thought this would be the correct place :

http://stackoverflow.com/questions/14150481/web2py-premature-end-of-script-headers-wsgihandler-py-apache-eating-cpu-9

Here is the flow :

1.) User visits the default/index.html

2.) Accessing this index.html isn't a problem either

3.) When the data is shown on iphone in ListView and I click on an item, that is when suddenly the cpu spikes.

When I click on an item, the controller function called "getLinkPages" is called. I've removed all code from this function which accesses the database, it simply returns hardcoded strings.

Some more info. in case it helps :
OS : Ubuntu 12.04 LTS
Memory : 512 MB RAM
Web2py version : Version 1.99.7 (2012-03-04 22:12:08) stable
psycopg2 version : 2.4.5

Here is the error shown in apache's error.log :

"Premature end of script headers: wsgihandler.py referrer http://sitename.com"

Here is what I have in my file inside sites-available :

I thought making "processes=5 threads=1" might at least alleviate the issue, since currently only I'm accessing it.

Neither has --> WSGIApplicationGroup %{GLOBAL}

• Am I doing something incorrect here while using JQuery mobile ?
  
• Any other logs I can enable to dig deeper ?
