Why is utserver aka uTorrent Server keeps crashing on ubuntu VPS

Question

I have ubuntu 12.04 32 bit VPS with 1GB ram, I have installed latest utserver utorrent-server-alpha-v3_3 from utorrent.com and using it as daemon

But every now and then utserver keeps crashing after few hours for no specific reason.

I have created a cronjob to check whether utserver is running or not , and running it every minute, if its not running then cronjob starts utserver as daemon. and mails me system info .

e.g. At the time of crash stats
