Receiving random cron generated emails

bbop

Hi - sometimes I receive sporadic emails generated by osTicket with such subject lines and messages:

Example #1:
Subject: Cron <root@server> /usr/bin/php /path/to/osticket/api/cron.php
Message: didn't trigger

Example #2:
Subject: Cron <root@server> /usr/bin/php /path/to/osticket/api/cron.php
Message: PHP Warning: stream_socket_client(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /../osTicket-v1.14.8/include/pear/Net/Socket.php on line 166
PHP Warning: stream_socket_client(): unable to connect to smtp.office365.com:587 (php_network_getaddresses: getaddrinfo failed: Name or service not known) in /../osTicket-v1.14.8/include/pear/Net/Socket.php on line 166

I am not sure why these are being generated. Sometimes for example #2, I receive incessant emails every 2 minutes for a while. I can only assume it means it can't send mail via office 365 sometimes (too many attempts?).

Example #1 I checked my apache error log (in osticket/log/error.log) and saw
[php7:notice] [pid 25329 (<--apache)] [client myremoteipaddress:51536] didn't trigger , referer: https://osTicketaddress.com/scp/tickets.php?a=open&uid=69

but not really sure what this is insinuating.

Is the cron part just how osTicket sends email, and what it's really sending me are apache errors? or are they PHP errors?

The error you are getting is php_network_getaddresses: getaddrinfo failed: Name or service not known. This means PHP could not find the network addresses for the supplied domain name (smtp.office365.com). You could be having DNS issues, PHP-FPM issues, or something else entirely. You will need to figure out what's going on on your server and address the underlying issues. Once those issues are addresses the error(s) should go away.

Cron is what triggers the system to automatically fetch email and to run cron tasks such as database cleanup, etc.

Cheers.

KevinTheJedi Excellent, thanks I will investigate that.
As far as the first example, I started receiving this email when I installed a Slack plugin for osTicket. So now whenever an email is generated by osTicket, as well as the slack message, I get this second email that says "didn't trigger"

Ahh okay that’s a 3rd party plugin that we did not develop nor do we support. You’ll have to reach out to the author of the plugin for further assistance on that part.

Cheers.

Yes, but the email is being generated by osTicket via /usr/bin/php /path/to/osticket/api/cron.php

Yes but the plugin could be triggered on the cron run and then generates the error. Please try uninstalling the plugin completely and retest.

Cheers.
