Where to find system logs?
Is there exist any linux OS logs, that could be useful for me while finding out what went wrong on software process level, what is/went wrong on the OS drivers level, especially regarding the network drivers, and so on.
The reason for this question is that I am running a Java application inside Tomcat, and there are some problems I experience from time to time, like JVM processes or threads hangs/freezes, JVM process abnormal terminations and others.
The command cat /proc/version returned following result:
Linux version 2.6.9-42.ELsmp (email@example.com) (gcc version 3.4.6 20060404 (Red Hat 3.4.6-2)) #1 SMP Wed Jul 12 23:27:17 EDT 2006
So I guess it is Red Hat system I am talking about (yes, this is remote third-party server with limited information and access right for me, but I can requested the needed logs).
