I have an Eq10 server from Hetzner. I'm facing this weird problem - the server responds to ping request without any loss; but it does not respond to ssh, http, ftp etc. Assuming the server is locked out, I try to use robot's reset - ctrl+alt+del and hardware - but none of these seem to reset the server. The server continues to ping without any loss during the reset.
I assumed the hardware reset generally overrides any software load issues in which server becomes unresponsive. A manual reset seem to bring it back online. And then when I run the 'sar -q' command to check the load, the average 5 min and 15 min load prior to reset /reboot is below 1.00.
