James Bench created IGNITE-1551: ----------------------------------- Summary: IgniteCache.put hangs indefinatly Key: IGNITE-1551 URL: https://issues.apache.org/jira/browse/IGNITE-1551 Project: Ignite Issue Type: Bug Components: cache Environment: Ubuntu 14.04 java version "1.8.0_51" Java(TM) SE Runtime Environment (build 1.8.0_51-b16) Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode) Tomcat 7 Reporter: James Bench
We have a process that pulls jobs from a queue and puts associated assets into a cache using IgniteCache.put. The object we put into the cache is an object holding a map of Enums and byte arrays. {code} private Map<AssetTypeEnum, byte[]> assets = new EnumMap<>(AssetTypeEnum.class); {code} We are using a UUID as the key. The byte arrays can become quite large - the batch it was processing when the issue occurred were up to 30mb in size. The thread got stuck in {code}IgniteCache.put{code} and remained stuck for a few hours until we restarted Tomcat. I took a memory Snapshot using YourKit while the application was frozen (attached) which shows the thread {{taskExecutorBean-3}} waiting in sun.misc.Unsafe.park. It has spent 100% of the time I profiled here. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
