if it doesnt affect the agent then perhaps we are suffering from two different problems as each agent with that problem also shows as being not available in the zabbix server page. Agents without that problem show as available.

Could this be related at all? We can telnet to port 10050 on each of the agents from the zabbix box, so communication isnt the issue.

I am pretty sure it does not affect functionality of the agent. Please could you try release 4496 or higher (32 bit version only, 64 bit agent was not recompiled) when it becomes available at http://www.zabbix.com/developers.php and report if it works.

I would appreciate this very much!

Hi, Alexei.
I have this problem too ( Call to PdhCollectQueryData() failed: No data to return.)
I have just installed Pre 1.4.2 (stable) 4499 - Windows 2003 Sp1.
I have no this error. Thank you.

I will wait version 64 bit agent.

I have tested the win32 agent of 1.4.2pre on a W2k3SP2 and it still stops to report the values to the ZABBIX server. This time, I have been lucky to get the part in the agent log file.

When everything is OK, the log shows

I can't tell what exactly happens to the agent. It seems to me, that it tries to process a second time the active checks and can't succeed.

Any ideas ?

Hallo all

I'm still having the problem with the agent and server of 1.4.2 stable.

Any news on this ?

Andreas

**swaterhouse** · 23-08-2007, 14:28

I am not seeing any issues like this on Win 2000, and Win 2003 (both 32bit and 64bit).

Is this just one agent that has an issue?

**Andreas Bollhalder** · 24-08-2007, 07:32

Yes, I have about 50 servers with the ZABBIX agent and the problem shows up only on one of them. The problem has been for all version I tried.

Andreas

**NB-beheer** · 28-08-2007, 09:12

I installed the 1.4.2 Windows client. Still the same problem.

Yeah, I was already looking where my previous post was

It's #17. The message on the server side is the same.
I've now turned on level 5 debugging on the clients. It was reset because of the installation of 1.4.2.
I'll post results when one of the clients hang again. It's actually two servers out of ten which have this problem. All are Windows 2003.

**Alexei** · 28-08-2007, 09:37

So, you are talking about these messages, right?

Code:

I do not believe 1.4.2 agent still generates them...

Agreed. I don't see those anymore.
Looks like there were two separate problems. One is solved by 1.4.2.
I'll post logfiles as soon as it hangs again.

**NB-beheer** · 29-08-2007, 11:58

See attachment from our Windows client.
At 0:34 the server sent an unreachable message.

Yesterday i have done the upgrade from 1.4.1 to 1.4.2 without any problems.
On my WIN2K3 Servers with zabbix agent 1.4.2 the PdhCollectQueryData() entries are NOT longer in the log file.

It seems to be fixed.

But the wrong swap size values from windows are still present.
