High CPU usage on Juniper EX4300 virtual chassis

yep, you can make poller debug with this device_id (but this not make sense for issue, since you revert firmware version):

./poller.php -d -r -h 19

mysql> SELECT `device_id` FROM `devices` WHERE `disabled` = 0 AND `hostname` LIKE 'ex4300-vc.mngmt.pardubice.cmnet.cz' AND `poller_id` = '0' ORDER BY `device_id` ASC;
-----------
| device_id |
-----------
|        19 |
-----------
1 row in set (0.00 sec)

Please go to page: device -> performance data
and make screenshot of page.

still not:

SQL[SELECT `device_id` FROM `devices` WHERE `disabled` = 0 AND `hostname` LIKE 'ex4300-vc.mngmt.pardubice.cmnet.cz' AND `poller_id` = '0' ORDER BY `device_id` ASC]

show me device page in observium.

Is that ok now?

I had to rollback to Junos 14, if it doesn't mind.
