18.2. Procedure – Creating syslog-ng core files

Purpose: 

When syslog-ng crashes for some reason, it can create a core file that contains important troubleshooting information. To enable core files, complete the following procedure:

Steps: 

  1. Core files are produced only if the maximum core file size ulimit is set to a high value in the init script of syslog-ng.Add the following line to the init script of syslog-ng:

    ulimit -c unlimited
  2. Verify that syslog-ng has permissions to write the directory it is started from, for example /opt/syslog-ng/sbin/.

  3. If syslog-ng crashes, it will create a core file in the directory syslog-ng was started from.

  4. To test that syslog-ng can create a core file, you can create a crash manually. For this, determine the PID of syslog-ng (for example using the ps -All|grep syslog-ng command), then issue the following command: kill -ABRT <syslog-ng pid>

    This should create a core file in the current working directory.
