Warning while upgrading system in Openhabian, Crontab limit

  • Platform information:
    • Hardware: Raspberry Pi 3B+
    • OS: OpenHabian 2.4 stable
  • Issue of the topic:
    While using the Openhabian-Config, “Upgrade System” utility, I received the following auto-generated e-mail while the update was running:
cron (3.0pl1-127+deb8u2) jessie-security; urgency=medium

  * As a reasonable protective measure, crontabs are now limited to 1000 lines
    in length per crontab.
    The maintainers find it very unlikely that longer crontabs exist; however,
    if you do have a use case, please file a bug report with a brief rationale,
    and we will consider raising this limit.

I have very few rules in Openhab that runs on a cron trigger, but I don’t think this is the cause. Can someone explain what this means and what I can do to correct it? I have never heard of crontabs before, but have done some quick research, and when I tried to list the crontab (crontab -l)I get:

no crontab for openhabian

System seems to be running as it should, so I am not sure what is going on here. Any help is appreciated.



This is probably just a warning because Cron was among the packages that got upgraded, and has nothing to do with openhab or openhabian.

Thanks for the info @pacive, this is the only time I’ve seen this error.
