    Description

      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
