[ASK] Poller is out of sync with Scheduled Task

[zetoo]

Currently my Poller is working but sometimes Poller Warning will appear such as :

- Scheduled Task is out of sync with the Poller Interval.

After this poller warning is appeared, poller will works again but the RRDProcesses will be reduced (for me: 47 => 32 => 27)

I checked some configuration :
- NTFS Permission for Spine.exe and RRDTool.exe is read/execute for user.
- Interval for Cron, Poller and Task Scheduler is 5 minutes = 300 seconds.

My technical supports :
Cacti 1.1.16
Spine 1.1.13
RRDTool 1.4.5 VC10
Net-SNMP 5.5.0-2
MySQL 5.7.16
PHP 5.5.33
IIS 8.5
Window Server 2012

Could someone help me to point out what is wrong ?

Updated issue.
After those warning log occur, poller works again perfectly without any error.

are you manually running poller.php or are there multiple scheduled tasks? Appears something is occasionally invoking it

Currently, I run those graphs using 1 task scheduler named Poller.
All graph template interval for Spine, Cron and Task Scheduler is 5 minutes.
BSOD, should I separate them in multiple tasks ?

After changing some spine settings, RRDsProcessed back to 47 again even though theres a poller warning.
Even though today morning, it happen to be processed RRDs from 47 => 5 => 42 => 47.

Naw, one scheduled task is correct.

Using any custom scripts or all the queries SNMP? Often scripts can hang, which then causes the poller to hang and run longer than 5 minutes.
if you increase the logging level a bit, you might be able to see why the rrd count changes to dramatically.

Its fine already, what I do is just increasing the 'Spine Specific Execution Parameters'.
