> If using MDC logging and splitting a large amount of data it could cause OutOfMemory because internal memory consumption for MDC is growing enormous.
> DefaultReactiveExecutor.Worker.back in HeapDump seems to be correlated with MDCCallback
> See test case  [^Main.java]  run with -Xmx1G -XX:+HeapDumpOnOutOfMemoryError
