I also getting this error sometime and as a worst case I also cannot open particular rooms. The troubleshooting from my side is to rename under userprofile the respective folder (e.g 8.2.12-.....) in .isxo directory (e.g. c:\Users\\.isxo\8.2.12........). It will reset the locally cached files.

However I would like to also know what is causing the problem.

Anyone from Schneider can help?

Hi Jef

Thanks for the link.

I have uploaded items 1 and 2.

I cannot provide the servers logs as the folder is empty and does not show any ETL`s.

Please let me know if you need anything else.

Kind regards

Paolo

Hi Paolo,

It seems the client application.log file is not uploaded (I could see the server logs and backup file). Client application.log file may contain the information I'm looking for, could you please upload it as well, thanks.

Usually located in windows client C:\Users\\.isxo\8.*\Operations\application.log

Kind regards

Hi Paolo (Paolo Sidoli),

Just let you know that I'm still waiting for the client application.log file, or perhaps the issue is resolved?

Kind regards

Hi Paolo,

Many thanks for the data/logs. I have checked the backup file/setup without any problem and could easily open every single room with no issues at all. Wondering if you still have issues opening a certain room?

However, according to the client logs it seems you/user are/is trying to move some equipment using the arrow keys on the floor view. But/apparently it happens that the equipment cannot find a "grid" to "snap" to, eg. from the equipment point of view there seem to be no tile/grid in the room. I will register an enhancement case for this.

And concerning the client freeze, it might/could be client resource related (memory usage, etc), eg. depending on the running/open applications in background and also if a lot of rooms being opened (in DCO). 

Kind regards

Hi Jef

Happy new year.  Apologies for the delay getting back to you.

Thank you for looking into this.

Yesterday I upgraded to 8.2.8 and that has managed to stop the java errors and freezing.  Over the coming days I will upgrade to 8.2.12.

If I do get any errors running on this version I will let you know.

Regards

Paolo
