I am experiencing the same problem with Ignite 2.1 when I have persistence configured. I can start a single node successfully (I have 1M entries persisted) but a second identical node fails with the error.
SEVERE: Failed to reinitialize local partitions (preloading will be stopped): GridDhtPartitionExchangeId [topVer=AffinityTopologyVersion [topVer=2, minorTopVer=0], nodeId=424cc634, evt=NODE_JOINED] java.lang.OutOfMemoryError at sun.misc.Unsafe.allocateMemory(Native Method) at org.apache.ignite.internal.util.GridUnsafe.allocateMemory(GridUnsafe.java:1054) at org.apache.ignite.internal.mem.unsafe.UnsafeMemoryProvider.nextRegion(UnsafeMemoryProvider.java:80) at org.apache.ignite.internal.processors.cache.persistence.pagemem.PageMemoryImpl.start(PageMemoryImpl.java:276) I have tried configuring a MemoryConfiguration with a DefaultRegion. I have plenty of RAM for the data - and indeed the first node starts without problem. Regards, Colin. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
