Broken Pipe

TomEE 8 / SmartGWT 12.1p

We get the following on the server:

It happens when the browser client makes a GET call to https://myapp/sc/messaging?ts=1643654667993...

The realtime messaging appears to still be working correctly, but is there a setting we can configure to avoid these errors?

[Isomorphic]

This basically means that the client has dropped the connection, which is ordinary and expected - it happens anytime the browser navigates away mid-request, or if the client cancels a request, and in various other circumstances.

We are not in that stack - this is low-level IO stuff inside Tomcat - so we cannot squelch that message for you. You would need to look at the Tomcat docs and likely configure your logging system to not report this.
