Getting Error but no information about ONS1021

[former_member686053]

Hi,

I try to push some channel to specific client but client not get channels material ( dome pdf dopcument. sendlist)

I get this error:

ONS1021: Did not receive a valid response to the Run Channel Command from the Client, "d4e72489d74f3093", with Client GUID, "{e8fc069b-c726-39b2-b4ff-bbe6544b0415}", and Address "10.40.1.212". Read only 0 bytes when expecting 4 bytes

I searched KB and this forum but not a familiar information about this problem.

Can you help me?

Tevfik,

What service pack level are you running?  This sounds like an issue we corrected in Service Pack 7.  This is not a common error, it almost always has to do with network responsiveness.  If you are not yet on SP7 or 8 can you possibly update to ensure that you are seeing this on current code?

Honestly I dont have test environment.

And I get ONS error very seldom

For example, now I delete the client and re-enroll and push channel without error

Well I am glad it is a low volume issue.  What client type is this?  More or less what this error means is that the information being sent to the client isn't fully received.   It could be a buffer issue, or some other problem with the outbound communication.  Have you tried rebooting the Afaria server to clear the error?

My clients are fully android tablets

There is 765 client. Sometimes have to push app or session policy. So then I can face with bottleneck sometimes about BW or buffer etc.

I really need fine tune about BW throttling, caching and outbound notification.

And, nowadays dont restart afaria server.

In that case I would recommend tweaking the flow control settings.  I would try halving the number of connections over the same period.  It can be adjusted up and down if there are still errors but that is a good starting point.   The system may be close to the maximum it can handle when you do a full push and that could be causing this issue.  On the server >configuration>outbound notification, set the high water to ~250 and the low water to 200 and the max per time period to 300 and give that a try.

Thanx. I will try and observe it. What about BW throttling? Do I have to set it? necessarily?

[tracy_barkley]

This doesn't seem like a BW throttling issue, this more looks like overloading the IP stack.   Try the flow control for now, and we can investigate the throttling if you are having a lot of packet retries on your network.

My SP level is 5.

While upgrade from SP4 to SP5 I got too many problems. Thats why I am hesitated to upgrade.

[tracy_barkley]

I underdstand but SP5 had a lot of changes in it, where the Sp5 to SP7 jump is less difficult.   Do you possibly have a QA environment where you can test the update?

How often do you see the ONS message?
