After rebooting the machine.
The mongo Server fails while starting with --journal argument.

Here the log data:
createPrivateMap failed /data/db/production.5 errno:8 Für diesen Befehl ist nicht genügend Speicher verfügbar. filelen:536608768 (32 bit build)
Fri Nov 18 15:32:48 [conn2] Assertion: 13636:file /data/db/production.5 open/create failed in createPrivateMap (look in log for more information)
Fri Nov 18 15:32:48 [conn2] command admin.$cmd command:

ntoreturn:1 exception: file /data/db/production.5 open/create failed in createPrivateMap (look in log for more information) code:13636 reslen:205 142ms

The translation for:
Für diesen Befehl ist nicht genügend Speicher verfügbar.
should be:
Not enough storage is available to process this command

If i start the mongo server without the --journal argument the server starts correctly.
But unfortunately with lost data in a collection.
