Good afternoon.
Periodically (+- once a week) the weblogic process crashes on the server under CentOS, it's just written "killed" in the console and that's it, the service logs reviewed everything, found nothing. Tell me how to identify the cause of this behavior in the logs or somewhere else?
OOMKiller has nothing to do with it, there is an excess of RAM in the system.

It was solved as follows: in the weblogic web console --> Settings for AdminServer --> Control --> Start\Stop set the value for Server LifeCycle Timeout to 120 seconds, it was 30.
Thank you all!

Start the process in debug from under gdb and analyze the crash dump.
Be careful, it can take up disk space, and it will be slower to work from under gdb.

It rather means that the process was terminated by a signal ("The program performed an illegal operation and will be closed"). You will have to google for a long time and look at the settings that you can twist.
