[ https://issues.jboss.org/browse/ISPN-8454?page=com.atlassian.jira.plugin.... ] William Burns commented on ISPN-8454: ------------------------------------- This only ever happens if reads are done with writes. If a ton of writes are done this isn't an issue. I was able to get the following exception to be thrown as well: {quote} Caused by: java.lang.AssertionError at org.infinispan.container.offheap.BoundedOffHeapDataContainer.removeNode(BoundedOffHeapDataContainer.java:152) at org.infinispan.container.offheap.BoundedOffHeapDataContainer.entryReplaced(BoundedOffHeapDataContainer.java:76) at org.infinispan.container.offheap.OffHeapDataContainer.performPut(OffHeapDataContainer.java:207) at org.infinispan.container.offheap.OffHeapDataContainer.put(OffHeapDataContainer.java:177) at org.infinispan.container.offheap.BoundedOffHeapDataContainer.put(BoundedOffHeapDataContainer.java:51) at org.infinispan.container.offheap.BoundedOffHeapDataContainer.put(BoundedOffHeapDataContainer.java:27) at org.infinispan.container.offheap.OffHeapSingleNodeStressTest.lambda$testLotsOfPutsAndReads$0(OffHeapSingleNodeStressTest.java:64) at java.util.concurrent.FutureTask.run(FutureTask.java:266) {quote} -- This message was sent by Atlassian JIRA (v7.5.0#75005)
