Hi
I’ve troubble with serveral poolers that does not update. I’m at a complete loss at what to do. The problem started after migration to a new virtual machine from a old one (From Ubuntu 18.04.3 LTS to 19.10, from PHP 7.2 to PHP 7.3)
root@server:/opt/librenms# ./validate.php
| Component | Version |
|---|---|
| LibreNMS | 1.56-46-ga782efe7f |
| DB Schema | 2019_10_03_211702_serialize_config (145) |
| PHP | 7.3.8-1 |
| MySQL | 10.3.17-MariaDB-1 |
| RRDTool | 1.7.1 |
| SNMP | NET-SNMP 5.7.3 |
| ==================================== |
[OK] Composer Version: 1.9.0
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct
[FAIL] The poller (ek-server) has not completed within the last 5 minutes, check the cron job.
[FAIL] The poller (librenms) has not completed within the last 5 minutes, check the cron job.
[FAIL] The poller (server) has not completed within the last 5 minutes, check the cron job.
Thank you so much for any help you can give.
I’ve tried to look a previous topics with same title, but the fixes there didn’t help me.
It didn’t help to remove “librenms” from the nonroot cron job, I’ve restarted cron and rebooted to server serveral times, no improvements 
I’ve tried to delete extra poolers, no difference.
I hope very very much that someone have an idea of what might be wrong with the setup. I’ll be happy to provide any debugging information that I’ve failed to provide above.
