Hi, Currently I am using 6.4.2 version of Elastic Stack. Started seeing our logstash docker container exited with code 1. Upon troubleshooting logstash logs notices erros releated to memory. Exited with Status code 1 `{"log":"io.netty.util.internal.OutOfDirectMemoryError: failed to allocate 16777216 byte(s) of direct memory (used: 1036789213, max: 1037959168)\n","stream":"stdout","time":"2020-01-02T20:30:02.927550323Z"}` Assuming its problem with logstash JVM heap size, have increased it from 1GB to 4GB. My logstash Java options. environment: LS\_JAVA\_OPTS: "-Xmx4g -Xms4g" Still I am seeing same kind of errors. `{"log":"io.netty.util.internal.OutOfDirectMemoryError: failed to allocate 16777216 byte(s) of direct memory (used: 4225105174, max: 4225236992)\n","stream":"stdout","time":"2020-01-09T02:13:38.84879815Z"}` Could anyone please help? ---
