Monitoring Overview Page never loads

[agentguerry]

I am running the latest Zabbix on an HS22 IBM Blade with quad processors and 8 gb of Ram.

The Server handles 169 servers/agents.
I made no changes on the machine since, and all was working well, but today, when I click "monitoring>overview", I never get any data to show up in the web console.

I have checked on multiple Browsers and on different machines, logging in as different users, but it never seems to load.

I changed my refresh rate for the pages to 5 minutes, to allow ample time before page refreshes, but still, no data output.

It was working before.

I restarted mysql, httpd, zabbix server...

Any ideas here is appreciated.

Is zabbix_server really running ?
What's in zabbix_server.log ?
Do you see any activity on the DB server ?

Do you see any activity on the DB server ?

The db server and the zabbix server reside on the same machine/ip.

mysqld is running.

I have 2 zabbix servers running in two different locales. One works appropriately, which has about 12 agents/servers reporting, and the one that is not functioning, has 169 servers/agents connecting. The problem started on Monday of this week.

[agentguerry]

well... my second server that is set up in another vlan has the same issue.
is there something in a conf file that limits the number of agents to be displayed?

the first server that I built, which only has 7 agents/servers connecting to it still is functioning correctly. But the two latest, that hold about 400 servers to each, the "monitoring>overview" page never loads...

any ideas are appreciated.
