Hi,

Thanks all for the tons of replies and suggestions.

Possibly the system has run out of network buffer resources. Has the load/number of users been steadily increasing?

Network configurations determine the number of buffers available for network packets (of various different sizes) arriving and departing, and also the maximum number of connections.
Could be possible that the load/number of users steadily increased.
Network configurations in this sense means? Which file?
Maximum connections you mean maximum ssh connections allowed? I believe it is still at the system default which is 60.
A week or 2 earlier, there were few occurrences of where users were not able to login into the server due to too many ssh connections from one user which had root (0) privilege.

You need to tell us all what hardware this is, what O/S you are running and which version. Give us a clue!!
Machine model : HP RX7640 ia64
OS version : HPUX B11.23
CPU : 4 Physical, 8 Core
Memory : 128 G

I am not aware of any security scanning devices used in the server.

There was nothing in particular happening in the server at the time of the crash.

ssh-socks5-proxy-connect(1)					   User Commands				       ssh-socks5-proxy-connect(1)

NAME
ssh-socks5-proxy-connect - Secure Shell proxy for SOCKS5 SYNOPSIS
/usr/lib/ssh/ssh-socks5-proxy-connect [-h socks5_proxy_host] [-p socks5_proxy_port] connect_host connect_port DESCRIPTION
A proxy command for ssh(1) that uses SOCKS5 (RFC 1928). Typical use is where connections external to a network are only allowed via a socks gateway server. This proxy command does not provide any of the SOCKS5 authentication mechanisms defined in RFC 1928. Only anonymous connections are possi- ble. OPTIONS
The following options are supported: -h socks5_proxy_host Specifies the proxy web server through which to connect. Overrides the SOCKS5_SERVER environment variable. -p socks5_proxy_port Specifies the port on which the proxy web server runs. If not specified, port 80 is assumed. Overrides the SOCKS5_PORT environment variable. OPERANDS
The following operands are supported: socks5_proxy_host The host name or IP address (IPv4 or IPv6) of the proxy. socks5_proxy_port The numeric port number to connect to on socks5_proxy_host. connect_host The name of the remote host to which the socks gateway is to connect you. connect_port The numeric port number of the socks gateway to connect you to on connect_host. EXAMPLES
The recommended way to use a proxy connection command is to configure the ProxyCommand in ssh_config(4) (see Example 1 and Example 2). Example 3 shows how the proxy command can be specified on the command line when running ssh(1). Example 1: Setting the proxy from the environment The following example uses ssh-socks5-proxy-connect in ssh_config(4) when the proxy is set from the environment: Host playtime.foo.com ProxyCommand /usr/lib/ssh/ssh-socks5-proxy-connect playtime.foo.com 22 Example 2: Overriding proxy environment variables The following example uses ssh-socks5-proxy-connect in ssh_config(4) to override (or if not set) proxy environment variables: Host playtime.foo.com ProxyCommand /usr/lib/ssh/ssh-socks5-proxy-connect -h socks-gw -p 1080 playtime.foo.com 22 Example 3: Using the command line The following example uses ssh-socks5-proxy-connect from the ssh(1) command line: example$ ssh -o'ProxyCommand=/usr/lib/ssh/ssh-socks5-proxy-connect -h socks-gw -p 1080 playtime.foo.com 22' playtime.foo.com ENVIRONMENT VARIABLES
SOCKS5_SERVER Takes socks5_proxy_host operand to specify the default proxy host. SOCKS5_PORT Takes socks5_proxy_port operand to specify the default proxy port. EXIT STATUS
The following exit values are returned: 0 Successful completion. 1 An error occurred. ATTRIBUTES
