Resynchronizing UI by client's request.

Open imran-momin4041 opened this issue 3 years ago • 7 comments

I am getting below logs in my vaadin application

Resynchronizing UI by client's request. Under normal operations this should not happen and may indicate a bug in Vaadin platform. If you see this message regularly please open a bug report at https://github.com/vaadin/flow/issues.

I have use lot of threads in view and it runs simultaneously and each thread use manual server push

I am using Vaadin version (14.4.2)

When this issue happens it removes some components from browser.

Hello @imran-momin4041 , thank you for reporting the issue!

Could you please provide more details, so we can reproduce and find the root cause of the problem:

  1. Example project/app which reproduces the issue and the steps how to reproduce it
  2. Are there any observations in app behaviour except this warn message and "removes some components from browser"? Any error messages in the server's log, browser errors, loading indicator hanging etc.?
  3. OS and browser types and versions also would help.

Also, please try it with the latest Vaadin LTS - 14.6.8.

Thanks @sombochea for reporting this. Could you please provide more details, so we can start investigate the root cause. Since we don't know exactly what is the root cause of this kind of problems, we added "Resynchronizing UI by client's request" error message to fails fast and then to collect the necessary input data for investigation.

Hi, @mshabarov

I think, the root caused of this problem from client slow connection. And I also using thread with UI access with client. When client trying to get resources from server, it's pending requests and and some requests will response back broken UIs

  • When connection too slow (~10KB)
