We have one user of our Vaadin application who experiences UI lockups at random but fairly frequent intervals. We haven’t been able to reproduce the issue or identify the root cause. (Vaadin 23.3.15)
In the most recent incident, this was captured in the Javascript log. Does this provide any pointers as to where the problem might lie?
