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.
