Hello, i'm Alessandro,
i've been working with a mongo server 2.04 on my ubuntu server 12.04 for almost one year with no problem,
then i needed to upgrade mongo to latest vers.
i made an apt-get upgrade but no new release found,
so i tried to uninstall and then i followed the guide http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/
after installation mongo server was down, and at each attempt to rise up the service i got this error on the log:

• • • • • SERVER RESTARTED *****

so i tried to upgrade ubuntu server to 13.04 as well,
but the issue didn't solve.

i searched the web for a solution but i didn't find any similar issue reported.

thanks for the attention,

Alessandro,
Rome
