Keeping the size of AutoSupport messages down

The AutoSupport message contains the /etc/messages file. If that file becomes too large, the size of the AutoSupport message can cause problems, especially if you are using the SMTP transport protocol. You should keep the size of AutoSupport messages down.


  1. Make sure that the /etc/messages file is being rotated on a weekly basis as expected. If necessary, rotate the file manually.
  2. Make sure you have your /etc/syslog.conf file to capture only system messages of level WARNING or above in the /etc/messages file.

    For more information about editing the /etc/syslog.conf file, see the na_syslog.conf(5) man page.

  3. Consider using HTTP or HTTPS for your AutoSupport transport protocol.
  4. If the above steps do not resolve the problem, you can set the autosupport.content option to minimal.

    Using the minimal setting is not advised, as it may impact the quality of your technical support.
