My machine abruptly report errors and immediately return to the Login Interface. (the errors are printed in the real terminal with cursor blinking too quick to capture a snapshot).
I re-log-in and check the syslog
$ head /var/log/syslog
May 13 05:22:54 alpha syslogd (GNU inetutils 1.9.4): restart

It prompt that GNU inetutils restart

The detailed information about the machine:
The problem occurred two or three times daily which does interrupt the work routine.
I tried months but failed to take a picture when it report errors in a real terminal.
How could I fix the problem? or retrieve the errors from log?
