Весенний облачный шлюз - io.netty.util.internal.OutOfDirectMemoryError

Я использую стек ниже

Spring Cloud Gateway Release Hoxton, Java 1.8, Linux ОС

Я вижу ниже исключение, которое исчезает после перезапуска, но снова появляется через некоторое время. Я не делал никаких явных настроек для прямой памяти. Ниже приведены аргументы JVM: 

-Xms512m -Xmx512m -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled -XX:CMSInitiatingOccupancyFraction=60 -XX:+UseCMSInitiatingOccupancyOnly -XX:+DisableExplicitGC -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=10240K -Xloggc:logs/gc.log0423_0751 -verbose:gc -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=logs -XX:+PrintStringTableStatistics -Djava.security.egd=file:///dev/./urandom -Dreactor.netty.http.server.accessLogEnabled=false

Может ли кто-нибудь посоветовать причину ошибки?
