What is the cause for the crash? Do you have a log or core for that?

Is any change in the IP address of the server upon restart?

Do the errors persist or they stop after a while? They are related to 
NAT keepalives sent by nathelper module, so they don't affect the sip 
traffic and if they are for stale contacts then they are fully harmless. 
The stale contacts should be automatically removed after a while by 
usrloc module.

Cheers,
Daniel
