Flux crashes in remote desktop

Recommended Posts

Hi, 

 

At work, I often work on Flux using Windows remote desktop, especially when I start a large batch of simulations, just to quickly check that everything is still running smoothly.

However, it happened from time to time that opening the remote session causes the active project window to simply vanish. It disappears and all processes are gone. Only the supervisor is still running.

 

That's pretty annoying and I'd like to know if anybody's encountered this issue.

 

Both machines run on Windows 10 Enterprise, x64.

 

Thanks, 

Romain

Hello Romain,

Actually, this is the first time that this bug is reported and it is very difficult to know the reasons with this information.

A possibility is that it is caused by an excessive requirement of HW units: in fact, run several projects in the same machine and with the same user requires less  HW units than running the same amount of projects distributed between different machines launched, possibly, by different users.

Best regards,

Hi Alejandro, 

Alright, thanks for the feedback.

I'll try to pay attention to our units usage next time this happens. Also I'll make sure to check the log file, see if there's any message on crash. However, I hope it just won't happen again :-)

 

Regards, 

Romain

Hi, 

 

Well it just happened again. There is no information in the log file. I can however describe a sequence of events:

1. Started a batch simulation on the remote computer (Windows 10 on both computers) using my scripts (by using the "run a script" button from Flux supervisor)

2. Connected several times to that computer through remote desktop using remote desktop to work on other geometries, and check on the advance of my simulation.

3. Connected physically on the remote machine (not through remote desktop), and there it is, the simulation window is gone, without an error message or any trace in the log file.

Funny thing is, the window where I was building a new geometry did not disappear.

 

I hope that this description helps, and I'm of course available for more details.

 

Thanks!

Romain

Hi Alejandro, 

 

It just happened again today. It crashed when I connected remotely using WiFi instead of the usual cabled connection. Strange.

Anyway, here is the logfile of that instance. I renamed the parameters, and only included the last few simulation steps because the original file is a million lines long. I have however not touched the log's or report's structure.

Hope it helps!

Thanks, 

Romain
