Problem saving wordpress settings with current version. Is it a bug?

Question

With the current version of wordpress 3.2.1 I am having this kinds of problem. I install wordpress frequently and I did not notice it before 3.2.1

Problem: Not being able to save settings under settings tab. The file names are options-general.php, options-writing.php, options-reading.php, options-discussion .php,options-privacy.php. Only settings that seems to be working is options-permalink.php. When I press the save settings button its just keep going and after couple of minutes its says "connection was reset" and some time with a "500 internal server error".

However options.php page is also okey infact i am currently using it to same those information.

Observations:

1. Hosting: Tested in different hosting "inmotion", "hostgator" "godaddy".
2. Technical info: All of those wordpress runs on Linux and apache.
3. Browser: I know its not a browser issue but still i tested it with different browsers Firefox and Chrome.
4. Theme installed: Some of those sites are using default 2011 theme and some custom theme. So, I don't think its a problem with theme.
5. Plugins: Tested with fresh wordpress install with no plugin/with plugin.

UPDATE:

Just downloaded the wordpress 3.2.1 zip file from wordpress.org and installed it to my localhost. Its seems fine in my local computer. But still having problem with wordpress in server.
