This weekend there was a sudden application crash in the server.
I did not know where to start to investigate the problem, so I first looked into the /var/adm/syslog/syslog.log, and this was what I found :
The error that is most related to this problem is "No buffer space available".
When I googled this error, there was no solid solution, some say memory pressure, and some say check the kernel value "tcp_conn_request_max" but I do not see this value present at all in the server.

How do I investigate this problem, I need to know the RCA of it. Please help.
