I am running a java application using this wrapper service yajsw. The problem it just stopped without any error in its logs file. So I was wondering will there be any system log file which will indicate the cause of it going down?

Partial of the log file.

What is the application and do you have access to the source? –  Wesley Apr 6 '12 at 2:59

  • General Linux messages are logged at /var/log/messages
    • You may have a number of logs named messages* - the one that is simply named messages is the latest one. The other logs have a number after them that signify the date they were closed. For example, some of the logs on one of my servers are messages-20120401 and messages-20120325. It's up to you to decide which period of time the application crashed and therefore which log to sift through.
  • Kernel logs are at /var/log/kern.log (but that's highly unlikely to be your issue)

I am in var/log but which one to look into quite a number of it there? Any idea? –  user111196 Apr 6 '12 at 3:12
    
@user111196 I updated my answer. –  Wesley Apr 6 '12 at 3:15
    
I have updated the partial log file looks like there was a restart in the system right? –  user111196 Apr 6 '12 at 3:30
    
If its own log is too good for it, then it's extraordinarily unlikely that anything has been sent to syslog. Java applications almost never make use of syslog. –  Shane Madden Apr 6 '12 at 3:43
    
So based on the log file can it be decide what went wrong? –  user111196 Apr 6 '12 at 4:11
