Q:

SSH random crashing

The SSH is getting crashed randomly that i can't login, and sometimes i get kicked out of my session (port closed), i have to restart the SSH service or the Server to make it open again,
PORT   STATE  SERVICE
22/tcp closed ssh

ssh: connect to host x.x.x.x port 22: Connection refused

No logs shows anything on "auth.log" or "Syslog"
The file system was corrupted before due to creating Superblock in the future, but it was fixed, i am not sure if there is a relation!

A:

I found the issue was due to some tool developer used to change the server time into future times multiple times, that the filesystem got corrupted as while restarting i found the error "Superblock last write time is in the future message,
I used live Ubuntu CD, and using the fsck -yf /dev/sdx, fixed the all drives, then everything worked fine,
