Error on startup for mongodb server - ruby-on-rails-3

totally new to mongodb. I'm trying to install locomotive CMS on my server, which is cool, but I've always used SQL/MySQL so mongo is totally new to me.
I installed all the needed mongodb modules, but when I run: sudo service mongod start I get an error code. When I look in the logs for the error, here is what is output:

Also, I run: sudo service mongod status and the output is mongod is stopped so I know it's not running.
Following the stack, it looks like the error has something to do with insufficient space, but my server has 15gb free and im running sudo, so i know it's not a permission error....how can I allocate more space...or better yet, what should i allocate more space to?
Any help is appreciated.

Add smallfiles = true to "/etc/mongodb.conf".
Now try to start the service, I assume this should fix the issue!!
Set to true to modify MongoDB to use a smaller default data file size. Specifically, smallfiles reduces the initial size for data files and limits them to 512 megabytes. The smallfiles setting also reduces the size of each journal files from 1 gigabyte to 128 megabytes.

Why does "~$ sudo openvpn ~/<file_name>.ovpn" give error?

I got a .ovpn file for work a couple of weeks ago and at first, everything worked correctly, it was running no problem. When I tried to use it again I got this error
<user>#<name>:~$ sudo openvpn ~/<file_name>.ovpn
Options error: In [CMD-LINE]:1: Error opening configuration file:
/home/<name>/<file_name>.ovpn
Use --help for more information.
So I tried openvpn --config <file_name>.ovpn and got this
<user>#<name>:~$ openvpn --config <file_name>.ovpn

Thanks in advance.
The problem most likely is that the port rabbitmq is trying to use is currently in use by another process.
This is stated in the output of journalctl -xe
... : Error during startup: {error,{could_not_start_listener,"::",5672,eaddrinuse}}
you can see all the ports currently in use on the machine with
$ lsof -i -P -n
or to check specifically for that port
$ lsof -i -P -n|grep 5672
so you could either kill the process using port 5672 or change the port used by rabbitmq

Is it related to Provisioning Profiles? I followed Somewhat-same-issue this post and checked the file as suggested but its still the same.
Has anyone else been facing this issue?
Any help will be much appreciated. Thanks.
So the problem was with the Device Profile.
I forgot to add my iPod Touch in the Device list.
Member Center > Certificates > Devices > Add new device . Voila. Everything started working.

XCode 4 Crash but not sure why?

XCode4 just crash on me when I was testing my app without saying why. I put the crash log I found on the device below. The app runs fine in the simulation so I am thinking it's the memory problem? I check for leaks but there is nothing serious to it, also there is not memory warning call.
The log said "Saved crashreport to /Library/Logs/CrashReporter/LowMemory-2011-06-01-154632.plist" but I can't find it anywhere on my mac.
Please help,
