Greetingz!

Well, without some kind of error logs or a little diagnostic information from you, it's going to be real hard to determine what caused your sshd daemon to die. Just a wild, completely irrelavent guess, but I'd say this is probably the root cause.

Please do the following (next time this "crash" thing happens).

1) "uptime", then give us the output.
2) "dmesg" and give us the output.
3) /whatever/syslog/logs/to: browse through it and give us the relavent chunks.
4) Maybe if you see an error you maybe take a google at it and see if there's already a solution?

WARNING: If you're going to post large amounts of output here, be sure to put [code] & [/code] at the beginning and end of your outputs! If you don't, your post will be so huge, that no one's going to bother to scroll through it (even me, and I love reading).

Solving Ways :
1 - Check it MRTG , PRTG graph ;
2 - look up nginx logs ,
3 - Look startup services ...

Best Regards ...
