Zabbix Agent and PFsense 2.0

[rmiddle]

I installed the package even though it said 1.2.3 and it seems to install fine but now getting the following errors in my agent log.

9618:20110128:005027.524 Item [ann100fw04.xxx.com:net.tcp.service[ssh]] error: Get value from agent failed: ZBX_TCP_READ() failed [Interrupted system call]

On suggestions for fixing?

Thanks
Robert
