You should not have so many pollers I believe, certainly not running from CMD.PHP. If you need more responsiveness switch to using Spine which is the compiled C version of the poller and operates far more efficiently.

FIXED after increasing PHP poller memory value. Very strange.

Yes what I can see there appears normal if you have your debugging set quite high.

Code: Select all

2018/01/10 05:38:10 - DBCALL DEVEL: SQL Cell: "SHOW TABLES LIKE 'plugin_hooks'"
2018/01/10 05:38:10 - DBCALL DEVEL: SQL Assoc: "SELECT ph.name, ph.file, ph.function FROM plugin_hooks AS ph LEFT JOIN plugin_config AS pc ON pc.directory = ph.name WHERE ph.status = 1 AND hook = ? ORDER BY pc.id ASC"

These two lines basically mean, check if the plugin_hooks table exists, and the second says find any plugins that match the desired hook. Since different hooks are passed through, you end up with multiple of those calls.
