Just upgraded to 12.1 and getting many 'cron' emails?

I just recently upgraded from 11.3 to 12.1 and am for some reason now getting my email appliance spammed with cron job emails. Any idea how to stop this? Since yesterday I have over 2,000 emails queued because the mail server doesn't recognize the domain name. Seems to happen every minute from the two F5 appliances.

Example of one email:

Subject: Cron  /sbin/lsusb -v -d 0451:3410 >/dev/null

  • This is bug ID578036. The command acts as a keepalive for the lcd panel, but the lsusb binary was moved, and the cron entry update was missed.

    You can work around it by doing this:


    */1 * * * * /sbin/lsusb -v -d 0451:3410 >/dev/null

    Change this to:

    */1 * * * * /usr/sbin/lsusb -v -d 0451:3410 >/dev/null

    The bug has already been fixed in 12.1.1, but I can not provide an indication on when that version will be released.

  • New issue with 12.1.1-HF2, mail err sSMTP messages and cron.hourly on standby unit:

    Subject: Cron  run-parts /etc/cron.hourly
    Reports scheduling should not run on a machine with a failover state of
    inactive or standby at /usr/share/avr/bin/ line 23.

    I haven't opened a case but quick fix add a " 2>&1" on to the end of the script:

    cat /etc/cron.hourly/avr_run_scheduled_reports
    /usr/share/avr/bin/ > /dev/null 2>&1
