FOG Client stops reporting & working

[Wayne Workman]

Ever since deploying the debug 0.11.5 client that Joe gave me, the issue has not reappeared. It’s been about 20 or so days, I think that’s plenty of time. It could be possible that it is a bug in the client, but at this point and being unable to reproduce, I think it’s a non issue.

For all those that experience the settings.json file going blank, just uninstall and reinstall the fog client. You might do this manually or with a very carefully crafted startup script via GPO, that checks for the presence of a dummy file to indicate if it should uninstall/reinstall or not.

@Wayne-Workman I also had this occur, oddly enough after running a snapin that forces the client to update via WSUS. I recently added .NET 4.6.1 to WSUS.

yup. here’s event viewer from that client

I got a bunch of “chinese” in my client log when this occurred

also had another warning saying something about registry being open and in use as well

Hope it helps guys.

[Joe Schmitt]

@Hanz where did that error log come from? Event viewer? If its from the client’s log please upload the entire log file.

[Hanz]

@Joe-Schmitt event viewer, I unfortunately lost that log after uninstall and reinstall of client…

reset token, and uninstall-reinstalled client

this isn’t it all unfortunately as I stated before, but I think most of the above is due to empty .json file.

all the “chinese/gibberish” was during the authentication portion when client first starts up…

[Wayne Workman]

@Hanz said in FOG Client stops reporting & working:

This is absolutely the same bug I and one other have experienced. The server address cannot be found because it is lost from the settings.json file, because the settings.json file gets completely wiped out.

The only difference? I don’t have WSUS here, and these computers in this building do not automatically update. We make a new image every summer for every model, and image everything every summer - so because of this we don’t worry about updates during the school year.

[Hanz]

@Wayne-Workman then, without updates, it seems like that would rule out the .NET framework updates…I will add that I only noticed this after changing from RC-23 to Tom’s working RC_24 candidate. After uninstall/reinstall the .json file was correct, then reboot wiped it. So far, after reverting to RC_23 doesn’t seem to exhibit this behavior after several reboots.

[Tom Elliott]

@Hanz I still disagree. Seeing as the images were updated then deployed I still lean towards .NET being the culprit, in what way I have no idea.

[Wayne Workman]

it’s all smoke and mirrors until someone finds a better clue.

[michael_f]

@Wayne-Workman Maybe i’ve got the clue. I too have a blanked settings.json file.

The windows eventlog shows an unexpected shutdown at 14:17:56

Windows Explorer shows, that settings.json was last changed at the same time

So I guess the file was opened to get updated while windows crashed.

[Joe Schmitt]

@michael_f A windows crash would explain it (especially if the disk was in the middle of a write request). I’ll push out a patch to try and address this issue.

[Joe Schmitt]

@michael_f @Wayne-Workman @Hanz a patch has been developed and verified for this issue. It will be released with 0.11.6 (along with a few other new features) once release candidate testing finishes for the client.
