Hi, I notice some of my elasticsearch containers do cyclic restarts after long service. docker logs show the following: Version:1.0 StartHTML:0000000105 EndHTML:0000039235 StartFragment:0000037910 EndFragment:0000039195 ``` OpenJDK 64-Bit Server VM warning: Insufficient space for shared memory file: 19 Try using the -Djava.io.tmpdir= option to select an alternate temp location. OpenJDK 64-Bit Server VM warning: Insufficient space for shared memory file: 1 Try using the -Djava.io.tmpdir= option to select an alternate temp location. ``` After this I have disabled java performance monitoring and changed location of tmp dir but I still see that hsperfdata directories are created under systems tmp directory. ``` bash-4.3# tree /tmp /tmp ├── hsperfdata_elasticsearch └── hsperfdata_root 2 directories, 0 files ``` One directory is created in new tmp dir: > bash-4.3# tree /elasticsearch/tmp/ > /elasticsearch/tmp/ > └── jna--1985354563 java is started with right options I believe: > bash-4.3# ps aux | grep java > 1 elastics 2:10 /usr/lib/jvm/java-1.8-openjdk/jre/bin/java -Xms6g -Xmx6g -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -server -Djava.awt.headless=true -Dfile.encoding=UTF-8 -Djna.nosys=true -Dio.netty.noUnsafe=true -Dio.netty.noKeySetOptimization=true -Dlog4j.shutdownHookEnabled=false -Dlog4j2.disable.jmx=true -Dlog4j.skipJansi=true -XX:+HeapDumpOnOutOfMemoryError -XX:-UsePerfData -Djava.io.tmpdir=/elasticsearch/tmp -Des.path.home=/usr/share/elasticsearch -cp /usr/share/elasticsearch/lib/\* org.elasticsearch.bootstrap.Elasticsearch Are there anything I can do about the hsperf directories under /tmp?
