Hi all,
I have a question about Linux OS.
My epics shell always shutdown itself in this computer, so the epics ioc could not run long time.
I do not quite know how the OS shutdown. I just know the ioc was shut down. I means that I don't know what happened.
I checked the log and found these information bellow.
I am not good at the linux OS, so I am here ask for help.
Could someone tell me how to fix it.
Regards,
Li xing
