After install this module Available Updates doesn't work

Ok, I did a fresh install of Drupal, activate String Override module and then activate one by one the others modules. I have now 25 active modules (total 60) and the admin/reports/updates page take a long time to check. When finally load this show randomly this message at the right side of the modules "No available releases found".

For example, some times simplemenu have this message and in another check not. If I activate more modules the check never refresh.

I realy like this module because this article say that this module increase the performance of the site instead of use the locale module.

thanks

Maybe I found the problem, notice the blank line in stringoverrides.info. I delete it and now the update run fine.

Sorry, but this about the blank line did nothing, when I activate more modules the problem still there.

I found this module:

http://drupal.org/project/update_advanced

and disable String Overrides for the check update.

Yes, my configuration already have 100MB but maybe SO consume more than others modules. The site work fine with 59 active modules, but when I enable SO the update system stop to work.
