zabbix agent returns GIOP as answer to zabbix_get command

[trikke]

Hi there,

I'v got a strange behaviour on one of our Agents.
If i execute: zabbix_get -s <hostname of Server> -k system.uname
the agent returns with: GIOP
The correct response should be somewhat in the line of:
Windows HOSTNAME 5.2.3790 Windows Server 2003 Service Pack 2 Intel IA-32

Does somebody has the same problems and/or behaviour?

I can't reproduce the problem, though it happens almost daily!
