All non stock apps are crashing Suddely without any previous event my application has started crashing. Only stock applications work? Cleared cache of some of them but nothing happened. Do you have any ideas, or I will have to make a factory reset?:S

EDIT!!!!

I have a great hint...I trie to reinstall an app and I got an error telling that there is insufficient space in my phone. Any ideas?:)
I have this happen from time to time. My issue is usually just about any application, not just "non-stock". 

To fix it I have to reboot in to the recovery and clear the cache. I believe that it has to do with the number of applications that I have installed, ~105 total, and the amount of data they store in the cache. 

Clearing the cache usually fixes it, but only for a short time, unless I remove some applications. I am now down to about 80 and I haven't had the issue in a couple weeks.
