[jira] [Commented] (IGNITE-8770) OutOfMemory in Queries1 suite in
master branch on TC
[ https://issues.apache.org/jira/browse/IGNITE-8770?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16613706#comment-16613706 ]
Alexey Platonov commented on IGNITE-8770:
-----------------------------------------
potentially OOM may appear due to large number of partitions
too many GridFutureAdapters in heap in straces like:
java.lang.Thread.getStackTrace(Thread.java:1559)
org.apache.ignite.internal.util.future.GridFutureAdapter.<init>(GridFutureAdapter.java:66)
org.apache.ignite.internal.processors.cache.distributed.dht.GridDhtLocalPartition$2.<init>(GridDhtLocalPartition.java:202)
org.apache.ignite.internal.processors.cache.distributed.dht.GridDhtLocalPartition.<init>(GridDhtLocalPartition.java:202)
org.apache.ignite.internal.processors.cache.distributed.dht.GridDhtPartitionTopologyImpl.getOrCreatePartition(GridDhtPartitionTopologyImpl.java:835)
org.apache.ignite.internal.processors.cache.distributed.dht.GridDhtPartitionTopologyImpl.initPartitions(GridDhtPartitionTopologyImpl.java:391)
org.apache.ignite.internal.processors.cache.distributed.dht.GridDhtPartitionTopologyImpl.beforeExchange(GridDhtPartitionTopologyImpl.java:566)
org.apache.ignite.internal.processors.cache.distributed.dht.preloader.GridDhtPartitionsExchangeFuture.distributedExchange(GridDhtPartitionsExchangeFuture.java:1265)
org.apache.ignite.internal.processors.cache.distributed.dht.preloader.GridDhtPartitionsExchangeFuture.init(GridDhtPartitionsExchangeFuture.java:766)
org.apache.ignite.internal.processors.cache.GridCachePartitionExchangeManager$ExchangeWorker.body0(GridCachePartitionExchangeManager.java:2577)
org.apache.ignite.internal.processors.cache.GridCachePartitionExchangeManager$ExchangeWorker.body(GridCachePartitionExchangeManager.java:2457)
org.apache.ignite.internal.util.worker.GridWorker.run(GridWorker.java:110)
java.lang.Thread.run(Thread.java:748)
for this reason I limit partitions count in test as first approximation of fix
