Hi Andrew, Below is the grid config <property name="discoverySpi"> <bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi"> <property name="ipFinder"> <bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder"> <property name="addresses"> <list> <value>10.179.29.135:47500..47509</value> <value>10.179.29.136:47500..47509</value> <value>10.179.29.137:47500..47509</value> </list> </property> </bean> </property> <property name="heartbeatFrequency" value="2000"/> <property name="maxMissedHeartbeats" value="5"/> <property name="reconnectCount" value="100"/> <property name="networkTimeout" value="10000"/> <property name="socketTimeout" value="10000"/> <property name="statisticsPrintFrequency" value="60000"/> </bean> </property>
<property name="communicationSpi"> <bean class="org.apache.ignite.spi.communication.tcp.TcpCommunicationSpi"> <property name="slowClientQueueLimit" value="18000"/> <property name="messageQueueLimit" value="20000"/> <property name="localPort" value="9090"/> <property name="connectTimeout" value="5000"/> <property name="idleConnectionTimeout" value="75000"/> <property name="sharedMemoryPort" value="-1"/> </bean> </property> I have not tried with less number of clients & increasing the number of servers. Please suggestion in this regard. Use case:- All the caches are storing session related data (such as login session and sso token management) which is created once, updating is not that frequent but accessing is 50 / 60 times. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Ignite-Cluster-going-OOM-tp15175p15186.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
