Server process in AS java got restarted

[Former Member]

Hi All,

I am trying to investigate as to why the server process got restarted.When i was having a glance in MMC it was having a uptime different from other server nodes in the system.At first i checked the default traces but it is very difficult to read the logs since it doesnot have any time.Which logs in the work directory should i be looking at.Thanks.

Hi,

Can you check std_server0.out ??

There should be somthing related to server node crashed

Hi,

Check dev_server, dev_disp, std_server* and bootstrap logs in the work directory for the time when server was restarted.

Also, check whether memory in your server is appropriate or not like heap memory because of which sometimes java got restarted.

Thanks

Sunny
