Hello everyone

For some time, I have a LINUX crash problem.
I have two Proview Stations running on virtual machines on two separate servers.
The Systems are MINT.
There is only Proview on it.
Java takes 100% of the CPU load which crashes the VM as well as Proview.
Have you ever had this problem?




Thanking you in advance for your help.

Cordially

Phil

Hi Phil,

We have seen this phenomena on an operator station. It's the websocket server that supplies the web interface with information that loops. We have made some adjustments and haven't seen if for some weeks now, but it's not very frequent so I'm not 100% sure that we found the cure. If you tell me what version you're running I could make a patch with the changes we have made.

Hello Claes,

Thank you for the feedback.
Indeed, I use the websocket server on my two operator stations.
I am using the latest version of Proview (6.0.0-1).

I also noticed that when I connect from an Android phone, I use a websocket connection. This one does not reset when I quit my browser on android. Suddenly I have already exceeded the 50 max connection, which forced me to restart the application.

Thanks for your help,

Phil

Hi Phil,

The patch is here

http://proview.se/v1/files/tmp/pwrrt_6.0.0_patch01.tar.gz

Unpack and copy pwr_rt.jar to $pwr_lib on the operator station.

Hello Claes,

Thank you so much.
I cant download the file.
should I stop the proview for the patch?

THANKS

Phil

Try again to download the file.

At least you need to restart the websockerserver.
Log in as pwrp and kill the process 'java jpwr.rt.GdhWebSocketServer'. Start again with
> rt_websocketserver.sh &
