I am running java application having Ignite 2.7.5 as dependency
*java -Xms4g -Xmx4g -XX:+AlwaysPreTouch -XX:+UseG1GC
-XX:+ScavengeBeforeFullGC -XX:+DisableExplicitGC -server
-XX:MaxMetaspaceSize=256m -XX:+HeapDumpOnOutOfMemoryError
-XX:+ExitOnOutOfMemoryError -jar
target/java_simple-1.0-SNAPSHOT-jar-with-dependencies.jar*
This application does nothing except running Ignite server.
I have specified max memory as 4g and also internal data region memory as ~
4g with eviction policy defined.
*DataRegionConfiguration regionCfg = new DataRegionConfiguration();
regionCfg.setName("chat"); regionCfg.setMaxSize(2000L *
1024*1024); regionCfg.setInitialSize(1100L * 1024 *1024);
regionCfg.setPageEvictionMode(DataPageEvictionMode.RANDOM_LRU);
regionCfg.setEvictionThreshold(.7);
regionCfg.setMetricsEnabled(true); DataRegionConfiguration
regionCfg2 = new DataRegionConfiguration();
regionCfg2.setName("btc"); regionCfg2.setMaxSize(2000L *
1024*1024); regionCfg2.setInitialSize(1100L * 1024 *1024);
regionCfg2.setPageEvictionMode(DataPageEvictionMode.RANDOM_LRU);
regionCfg2.setEvictionThreshold(.7);
regionCfg2.setMetricsEnabled(true);
storageCfg.setDataRegionConfigurations(regionCfg2, regionCfg);
cfg.setDataStorageConfiguration(storageCfg);*
I am hitting ignite server with 18 clients with average get/put/remove
operation of 2k hits per second.
System on which ignite is running has around 8G of ram.
When I run my clients[From different server] that hit the Ignite server for
few minutes, it consumes all my system RAM[Ignite server] and it stops
with OOM error.
I don't understand why it goes beyond the memory specified in the data
region.
Thanks & Regards,
