SOLVED Cloudron stops working periodically

    This is weird but here it goes :-).

    @tadeas I have validated your mail here. We got your email to support but it does not have a working email (the FROM address is not gmail) and it's thus bouncing. Please send us an email from your gmail account. Thanks.

  • Thanks 🙂 (I used to have g. apps for my domain for many years, which is still working to send emails from, even after I migrated to cloudron)

    Anyway, here's the issue ---

    I've been using cloudron for about 6 months now. Usually every 4 weeks I need to login via ssh and manually reboot, because the server stops responding (mail, calendar, etc.). I didn't have time to troubleshoot that.

    Now however, the mail&calendar became inaccessible and the my.* interface was saying update in progress for many hours. I rebooted and now I'm only getting an error page from the cloudron.

    Logging into the server via ssh, I see mysql is not working and also does not restart.

    Unbound service also not working, but starts if I restart it.

    I don't know how other services are doing.

    This happened by itself, I was not doing anything with the server. I can of course wipe the server, reinstall and load a backup, but I would prefer not to have this happen again.

    I have now wiped the server and am restoring from backup, I can have it offline for longer.

    But I will leave this here for future reference.

    Thanks, T.

    @tadeas It's hard to tell what is happening, are you able give us SSH access to the server? SSH keys are here -

    Can you also tell us:

    1. Does the server have sufficient disk space? If it ran out of disk space, please use the procedure here -

    2. What version of Cloudron are you running?

    3. Can you paste the output of "ls -lh /var/lib/mysql/box"? If you see the eventlog to be very large (like in gigs), that is probably the root of all the problems.



  • @girish Thanks for the response. I have wiped the server and did a restore, so I can't do what you suggest atm.

    There is/was plenty of space (42gb used out of 490), and ram (1gb out of 6gb).

    I was/am running 2.0.1.

    I'll check the event log size once the problem comes in again and will report here.
