Zabbix active agent check fails on 1 item

[jzondervan]

Hello,

Strange problem: Since today one of the windows-agents fails to check a service. It worked smoothly yesterday, nothing has changed. I already restarted the agent but no good.

Log shows this:

5180:20100722:110942.517 JSON before sending [{
"request":"agent data",
"data":[
{
"host":"BNIT01",
"key":"service_state[ekrn]",
"value":"0",

{
"host":"BNIT01",
"key":"system.cpu.util[]",
"value":"1.850000",

5180:20100722:110942.521 In check_response({
"response":"success",
"info":"Processed 1 Failed 1 Total 2 Seconds spent 0.000037"})

All other items work fine, it's just the service_state that produces no data. Anyone knows how to resolve this issue?

Solved it by deleting the item (disabling and activating did not work) and recreating it. Still worried, this shouldn't happen, should it?
