Rob Winch opened SPR-16555 and commented

There is a race condition on ChannelSendOperator.WriteBarrier.readyToWrite which prevents data from being written to the response.

This happens when using publishOn. From a Spring Security standpoint this means that the data written after a user authenticates is dropped randomly.

NOTE: smaldini has agreed to send a PR for this issue.

Affects: 5.0.4

Thanks for pushing the fix. I've ran my test for 24 hours x 3 processes now without reproducing the issue. I'm confident that this has resolved the problem I was experiencing. Please feel free to close this issue.
