[infinispan-issues] [JBoss JIRA] Commented: (ISPN-373) Deadlock between lock and put under heavy concurrency

Deadlock between lock and put under heavy concurrency ----------------------------------------------------- Key: ISPN-373 URL: https://jira.jboss.org/browse/ISPN-373 Project: Infinispan Issue Type: Bug Components: Locking and Concurrency Affects Versions: 4.0.0.Final Environment: Mac OS-X 10.6, 2.8Ghz Core 2, 8GB RAM Reporter: Nigel Slack-Smith Assignee: Vladimir Blagojevic Fix For: 4.2.0.CR1, 4.2.0.Final Attachments: DeadlockLockingTest.java Concurrent calls to lock and then put seem to be deadlocking. After AdvancedCache.lock is called under a transaction a subsequent call to Cache.put on the same key normally does not attempt to take out a lock, but after a variable number of concurrent calls Cache.put is attempting to take out a lock and then deadlocking with the AdvancedCache.lock call. Here's my test case which hits the deadlock. public class DataGridTest { @Test public void testCreate() { CacheManager cacheManager = new DefaultCacheManager(); final String cacheName = "TestCache"; Configuration config = new Configuration(); config.setTransactionManagerLookupClass("org.infinispan.transaction.lookup.DummyTransactionManagerLookup"); cacheManager.defineConfiguration(cacheName, config); final Cache<Object, Object> cache = cacheManager.getCache(cacheName); cache.start(); ExecutorService executorService = Executors.newFixedThreadPool(2); for (int i = 0; i < 1000000; ++i) { final String valueStr = "V" + i; executorService.execute(new Runnable() { @Override public void run() { TransactionManager txnMgr = cache.getAdvancedCache().getTransactionManager(); try { txnMgr.begin(); } catch (Exception e) { fail(e.getMessage()); } cache.getAdvancedCache().lock("K1"); cache.put("K1", valueStr); try { txnMgr.commit(); } catch (Exception e) { fail(e.getMessage()); } } }); } executorService.shutdown(); try { if (executorService.awaitTermination(300, TimeUnit.SECONDS) == false) { fail("Termination timeout"); } } catch (InterruptedException e) { fail("Thread interrupted exception: " + e.getMessage()); } } } ...and here's the stack trace showing what appears to be a deadlock timeout. 2010-03-16 08:35:57,821 1 ERROR [org.infinispan.interceptors.InvocationContextInterceptor] Execution error: org.infinispan.util.concurrent.TimeoutException: Unable to acquire lock after [10 seconds] on key [K1] for requestor [GlobalTransaction:<null>:114691]!
