Not getting data from polled items

[beomagi]

We have a lot of poller items setup in our environment, and i'm seeing that the items are being requested at the zabbix agent.

 19566:20160510:093335.526 EXECUTE_STR() command:'/appserver/zabbix_modules/zabora/xzabora \news \xz_news_cnt_3d \dn' len:3 cmd_result:'644'

But in zabbix i see the items show little or no data.


Is there a warning I should be looking for? When this happens I've found that changing the polling rate from 10 minutes to a minute causes the item to get requested and it does update.

I've tried looking at the server log, but don't see anything specific (max debugging). This is zabbix 2.4.4.
