[ https://issues.redhat.com/browse/ISPN-12423?page=com.atlassian.jira.plugi... ] Evgenii Balakhonov commented on ISPN-12423: ------------------------------------------- Hello, Will Burns I can reproduce this problem in any time. I can show it if you want, for example via Skype or TeamViewer And moreover. If I switch off OFF_HEAP and SYNC (see last attached cache-configuration-jdbc.xml) I have other problem with dead lock:  "[STUCK] ExecuteThread: '220' for queue: 'weblogic.kernel.Default (self-tuning)'" #812 daemon prio=1 os_prio=0 tid=0x00007ff29c136000 nid=0x4fb8 waiting on condition [0x00007ff1e281f000] java.lang.Thread.State: TIMED_WAITING (parking) at sun.misc.Unsafe.park(Native Method) - parking to wait for <0x00000006ec18b8a8> (a java.util.concurrent.CompletableFuture$Signaller) at java.util.concurrent.locks.LockSupport.parkNanos(LockSupport.java:215) at java.util.concurrent.CompletableFuture$Signaller.block(CompletableFuture.java:1709) at java.util.concurrent.ForkJoinPool.managedBlock(ForkJoinPool.java:3323) at java.util.concurrent.CompletableFuture.timedGet(CompletableFuture.java:1788) at java.util.concurrent.CompletableFuture.get(CompletableFuture.java:1928) at org.infinispan.util.concurrent.CompletableFutures.await(CompletableFutures.java:125) at org.infinispan.interceptors.impl.SimpleAsyncInvocationStage.get(SimpleAsyncInvocationStage.java:36) at org.infinispan.interceptors.impl.AsyncInterceptorChainImpl.invoke(AsyncInterceptorChainImpl.java:246) See attached thread dump "Thread dump - heap storage.txt". As a result my WebLogic server going to automatic restart because count of STUCK threads more than critical bound. As a temporary patch I changed class org.infinispan.interceptors.impl.SimpleAsyncInvocationStage: @Override public Object get() throws Throwable { try { return Objects.requireNonNull(future, "Completable Future must be non-null.") .get(10, TimeUnit.SECONDS); } catch (TimeoutException tme) { future.cancel(true); return null; } catch (ExecutionException e) { Throwable cause = e.getCause(); cause.addSuppressed(new TraceException()); throw cause; } } It works fine, but it is very dirty solution ;)   -- This message was sent by Atlassian Jira (v7.13.8#713008)
