Restart work most of time for these issue, but if issue happens in production we should have proper reason for justifying restart
Even i am not sure. I have heard from our architects telling unexpected behaviour of flow code, adapter services etc happens because of metadata got dropped(not sure what is metadata in IS)
Solution they suggested is increase perm size.Any idea what will happen, if we increase perm size?
Can disable then enable the connection fix your issue? The template information would be written to connection after itās initialized(or called enabled)
