SOLVED [CPANEL-24359] Inaccurate service failure notifications sent out when license is not valid

[mvandemar]

Starting roughly 3 hours ago I started getting hit with these messages from one of my servers:

Server    {servername}
Primary IP Address    XXX.XXX.XXX.XXX
Service Name    exim
Service Status    failed ⛔
Notification    The service “exim” appears to be down.
Service Check Method    The system failed to connect to this service’s TCP/IP port.
Reason    TCP Transaction Log:

Service Check Raw Output    The 'exim' service passed the check: exim (/usr/sbin/exim -ps -bd -q1h -oP /var/spool/exim/exim-daemon.pid) is running as mailnull with PID 17965 (systemd+/proc check method).

Log Messages    2018-12-17 03:11:12 exim 4.91 daemon started: pid=17965, -q1h, listening for SMTP on port 25 (IPv6 and IPv4) port 587 (IPv6 and IPv4) and for SMTPS on port 465 (IPv6 and IPv4)

I am getting them for both exim and imap, 48 in all over the past 3 hours (~8/hour each service). I am going to try rebooting the server to see if that helps, but any idea what would have caused this?

So apparently this was caused by the temporary cpanel license expiring. Is it supposed to spam those messages when that happens, or is that a bug?

Hello @mvandemar,

Internal case CPANEL-24359 is open to ensure service authentication via the mail server is possible in order for Chkservd to properly detect if the service is running in cases where the assigned cPanel license is invalid. I'll monitor this case and update this thread once it's published.

Thank you.

imap and exim failed.

Hello @vacancy,

I don't have a release date to provide for this case at this time, but the planned fix is currently in testing. In the meantime, the workaround is to ensure your license is valid. You can check your license status with the following command:

/usr/local/cpanel/cpkeyclt

Thank you.

I confirm that we are affected by this same exact issue. Currently we are at 76.0.14 when our license has expired.

Restarted IMAP service produces an error:

I'll try to provide an update after we fix the license issue and updated to 76.0.15.

Thanks @cPanelMichael !

As I promised with my last post, I confirm that the issue resolved after cPanel license has been updated.
