I think you have 2 options... go to Zabbix version 2.0.5 or follow this post:

system[procrunning] was the problem

After some logdiving i found that in one of our templates we where checking for: "system[procrunning]", and each time it did we got a "network error", and the host hung for 45 sec.
I disabled the item and voila ! no more "UNKNOWN" status on items.
I guess that while it was waiting to retry the failing item, our other items expired and becam "UNKNOWN"

This is how our log looked:
25799:20130422:124739.311 Zabbix agent item [system[procrunning]] on host [ns2] failed: first network error, wait for 45 seconds
25786:20130422:124740.336 Zabbix agent item [system[procrunning]] on host [lb4] failed: first network error, wait for 45 seconds
25798:20130422:124742.317 Zabbix agent item [system[procrunning]] on host [Prod15] failed: first network error, wait for 45 seconds
25765:20130422:124747.397 Zabbix agent item [system[procrunning]] on host [prod23] failed: first network error, wait for 45 seconds
25799:20130422:124748.531 Zabbix agent item [system[procrunning]] on host [Prod13] failed: first network error, wait for 45 seconds

Have a nice day !
