sshd daemon hung

Hi All,

I have faced a serious problem that none could login to the server using ssh. I ahve logged into GSP and done a stop and start of sshd.After that this issue got resolved. I could observe that before this issue occurs , all servers were not reachable for a few minutes. But I could able to ping to all servers. May be a network issue.

Can anyone suggest how sshd daemon hung? How do I investigate the root cause?
OS version is HP-UX 11.11 and ssh version is OpenSSL 0.9.7c 30 Sep 2003.

Please suggest a solution.

Hello,

I sugest that you set the "LogLevel DEBUG" in the sshd_config file, restart the daemon and then examine the log files.

Hi,

Have a look at the syslog around the time sshd was irresponsive. Look for errors that could go from network,memory,etc.

For example, just clients(thousands) reconnecting to a DB after a network problem, can starve your servers memory...

Windows?, no thanks
