Data not recorded for some seconds without a reason

[theomega]

Hy,
Zabbix sometimes doesnt record item-data for some time (2 minutes for example). This happens for every check which the agent on this server should execute, so its doesnt depend on the check.
There is no data at all, so neither a 1 nor a 0.

The log of the agent during this time is somehow strange:

normaly(!) is that:

  5201:20081101:001554 In check_security()
  5201:20081101:001554 Requested [vm.memory.size[cached]]
  5201:20081101:001554 Sending back [0]

but during the failure its like this:

  5203:20081101:000155 In send_buffer('::ffff:127.0.0.1','10051')
  5203:20081101:000155 Values in the buffer 0 Max 100
  5203:20081101:000155 Sleeping for 1 seconds

these lines repeat for the whole time, so no requests and no sending backs.

Where do I have to search for the error?

The missing data makes all triggers fire so its annoying and makes the monitoring useless.

Zabbix Version is 1.6 for both server and agent.

Thanks

Hello mate.

I was getting the same thing only with Windows Event Log monitoring. I upgraded to pre-1.6 and used the new agent and it all went away

Sorry i cant be of more help to you.
