I have a working Zabbix 1.8.2 server collecting data for our office and our colo facility. However the link between the colo and office is flaky. What I'm trying to do is setup a proxy on the colo side to have a 1 hour cache and relay the data to our primary server at the office. Our zabbix server is compiled from source and uses a mysql database

I've followed the instructions found in the zabbix documentation to compile the proxy using a sqlite3 database. I add the proxy to zabbix under Administration->DM->Proxies. The zabbix server "sees" the proxy because the "last seen" field is always under 60s. However when I assign a colo host to the proxy I stop receiving data from it. The colo host's zabbix_agentd.log file says this:

29343:20100622:124847 Timeout while answering request
29343:20100622:124847 Getting list of active checks failed. Will retry after 60 seconds

The zabbix_proxy.log says this.

2041:20100622:123131.760 Deleted 0 records from history [0.000994 seconds]
2028:20100622:124131.671 Error while receiving answer from server [ZBX_TCP_READ() failed 

I also am unable to receive any SNMP data which is more important to me than the zabbix agent data. Has anyone had this problem before?

Zabbix Server OS: CentOS5.4 Zabbix Server Build: 1.8.2 from source Zabbix Proxy OS: CentOS5.4 Zabbix Proxy Build: 1.8.2 from source

P.S. The SQLite database on the zabbix proxy never gets any data written to it, it is identical to when I created it from the blank schema in zabbix-1.8.2/create/schema. (Yes I've checked the permissions)
