Hi, I have deleted the logs for I want to do more test to make sure whether it's a issue. I run Ignite ver. 1.5.0-b1 with modified configuration , and now it have run smoothly for about one month. So I think it should be the TcpDiscoverySpi configuration problem.
The current configuration is : <property name="discoverySpi"> <bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi"> <property name="joinTimeout" value="0"/> <property name="ackTimeout" value="1000"/> <property name="socketTimeout" value="2000"/> <property name="networkTimeout" value="30000"/> <property name="reconnectCount" value="500"/> <property name="heartbeatFrequency" value="2000"/> <property name="maxMissedHeartbeats" value="5"/> <property name="ipFinder"> <bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder"> <property name="addresses"> <list> <value>10.1.XXXX:47500</value> <value>10.1.YYYY:47500</value> <value>10.1.ZZZZ:47500</value> </list> </property> </bean> </property> </bean> </property> Do you have any suggestions for best practices?
