MinimServer hanging after QNAP 4.3.3 Upgrade

[Atlantis]

Hi All,

After upgrading to QNAP 4.3.3 firmware, my most appreciated MinimServer keep on hanging after a while.

I have an Intel QNAP 469L. I tried reinstalling MinimServer 0.8.4.5, but that didn't solve the problem.

Below is one of the crash logs.

Any help is appreciated.

Thanks!

Please use MinimWatch to set the ohnet.debug property to Default+Network.

After the next failure, copy the minimserver.log file from the Public share of the QNAP to some other location. It is important to do this before you restart MinimServer.

I will PM you some instructions for uploading this saved log file to my FTP server. I will then look at it to try to find the cause of the problem.

[Atlantis]

Thank you!
Just followed the instructions and uploaded the log file.

[simoncn]

Many thanks. I will look at this file and post an update in the next few days.

[simoncn]

My apologies. You also need to set the logging level (in the log window) to Debug. Without this, the log file doesn't contain the necessary information.

Please can you do this again with these settings. You can close the log window after changing the logging level setting because the necessary information is written to the minimserver.log file rather than being displayed in the log window.

[Atlantis]

Thanks Simon. The new log with the Debug turned on is now uploaded.

[simoncn]

Thanks for this.

Unfortunately, it seems that this log file was produced without the Debug logging level being enabled. Please check your settings by doing the following:

1) In MinimWatch, select 'Show log' (not 'Options > Show log (watch)')
2) In the lower left corner of the log window, there is a setting for 'Logging level'. Check that this is set to Debug.
3) If the 'Logging level' property is not set to Debug, select this value in the drop-down box
4) Close the log window
5) In MinimWatch, select 'Properties' (not 'Options > Properties (watch)')
6) In the Properties window, select the System tab
7) Check the contents of the ohnet.debug field. This should be set to Default+Network.
8) If the ohnet.debug field is not set to Default+Network, type this value into the field and click the OK button

Many thanks.

Hi Simon,
I've followed your instructions and uploaded the new logs after the crash. I hope it will work this time
Regards

[simoncn]

Thanks for doing this. This log contains the information that I need.

In the log, I see some VPN activity. An adapter tun0 (10.8.0.1) is added and this is working OK. After this, another adapter tun2001 (10.7.7.16) is added and this is not working correctly with ohNet and MinimServer, leading to the crash. Please post your VPN configuration so that I can investigate further.

[Atlantis]

Thanks Simon.
tun2001 is TCP443 while the other is UDP connection.
The TCP connection did not have "Use default gateway on remote network" marked, while the UDP had it marked.
Could this be the issue? I turned on the option for TCP connection now.
