Issue still ongoing, there was a hotfix plus a replacement of a DLL that was sent to us. This did help with Framework/VL debugging. However the debugging of the WEB App's are still a issue. The debug gets to the first breakpoint, however when stepping down to the server modules and back causes ...

We had the same issues using a handheld device. We upgraded the firmware on the WIFI access point device and also set a fixed IP address on the handheld device. This solved the issue for us with regards to the performance (dropping out) of the PWA on the handheld device.

The issue went to LPC, we did get a hotfix but it did not fix anything. We still get intermittent access violation errors and are still unable to debug any web/mobile apps . The issue has gone back to LPC.

David, all passed over, thanks for adding your logs.

Also the x-err.log look just like yours the same error

Thanks for the reply, some good questions.
The vl web objects where compiled and checked in loads of times during development, it was only at the end that I wanted to test PWA app stuff so I added the offline support, as I was going to put the app onto a android device, but wanted to make sure it ...

If you are running on a iSeries, you can use a DTAARA on the server to store it.
