Reactor version: reactor-netty: 0.9.16.RELEASE reactor-core: 3.3.13.RELEASE @violetagg

violetagg commented 3 years ago

@yechao4j Please try to upgrade as there are fixes in the latest releases.

yechao4j commented 3 years ago

@violetagg netty: 0.9.20.RELEASE, core: 3.3.17.RELEASE?

violetagg commented 3 years ago

@yechao4j Reactor Netty is not enough, please consider updating the SCG version, which will pickup fixes in Spring Framework and SCG.

yechao4j commented 3 years ago

@violetagg Thanks, now i upgrade springboot version to 2.3.12.RELEASE, SpringCloud: Hoxton.SR11, which depend Reactor Netty version: 0.9.20.RELEASE, core: 3.3.17.RELEASE. Is that OK?

violetagg commented 3 years ago

@yechao4j yes these are the latest releases

yechao4j commented 3 years ago
