I am using Zabbix-1.8.5 on my servers and all along it was working properly but all of a sudden its now populating on some servers but not on some servers. i have checked all Zabbix_Agent on those servers and it seems everything is well. What might be the problem.

Hi and welcome to the Zabbix forums!
Zabbix 1.8.5 is really old and there were some performance improvements in like 1.8.10/11 IIRC.
I would recommend that you use the Zabbix Server template to monitor your Zabbix server, because it would provide valueable information regarding the performance of your Zabbix server. Like it would show you the % busy state of all its sub processes, which makes it easy to detect which part of Zabbix cannot cope any longer. Here's a nice blog about this: http://blog.zabbix.com/monitoring-ho...processes-are/
Without making any changes, you can already go to Administration > Queue to see the outstanding items, but that won't give you the reason as to why they weren't monitored in time.
Could you please post a screenshot (or text representation) of your Zabbix Dashboard's status part, which tells you how many hosts, items, triggers and new values per second Zabbix is doing.
Could you also give us your rough server specifications (CPU cores, RAM, HDD configuration) and what kind of hosts you're monitoring (SNMP / Active Zabbix Agent / Passive Zabbix Agent / Zabbix Trapper items / etc).
Lastly, did you leave all the Start* settings in your /etc/zabbix/zabbix_server.conf file on the default values, such as StartPollers=5?
It is very important to increase them if you have a large setup. The Zabbix Server template's results should indicate which of these settings need adjustment!
