(7.2.z) ISPN-9798 - Deadlock in org.infinispan.persistence.manager.PersistenceManagerImpl when using infinispan in Wildfly-14.0.1.Final

XMLWordPrintable

      We are using Infinispan-9.3.1.Final in Wildfly-14.0.1.Final.

      We have a local cache backed with a file store, the configuration is like this:

      <local-cache name="our-cache">
          <locking acquire-timeout="500"/>
          <object-memory size="80000"/>
          <file-store passivation="false" preload="true" purge="false"/>
      </local-cache>
      

      And in the code, we put into the cache with code like this:

      ourCache.put(key, value, 5, TimeUnit.MINUTES);     
      

      (We were doing this because in older version of Wildfly, the expiration timeout in the configuration file was not respected. The timeout in prod would be much higher than 5 minutes of course, just for demonstration purpose here).

      When Wildfly-14.0.1.Final boots up, if it has been down 5 minutes, all entries would be expired.

      And usually the number of requests that use the cache is really high, which ends up the following situation:

      Here is my understanding:

      1. "default task-6" locked "0x0000000719600070", then waiting for the read lock in # "PersistenceManagerImpl".
      2. "expiration-thread--p9-t1" grabbed read lock (based on the source code, it must have grabbed the read lock in order to reach locking "0x0000000719600070"), then waiting to lock "0x0000000719600070".
      3. "persistence-thread--p11-t4" would like to grab the write lock in order to continue.
      4. "PersistenceManagerImpl" uses "NonfairSync", based on this implementation in "ReentrantReadWriteLock" in openJDK-11.0.1
          /**
           * Nonfair version of Sync
           */
          static final class NonfairSync extends Sync {
              private static final long serialVersionUID = -8159625535654395037L;
              final boolean writerShouldBlock() {
                  return false; // writers can always barge
              }
              final boolean readerShouldBlock() {
                  /* As a heuristic to avoid indefinite writer starvation,
                   * block if the thread that momentarily appears to be head
                   * of queue, if one exists, is a waiting writer.  This is
                   * only a probabilistic effect since a new reader will not
                   * block if there is a waiting writer behind other enabled
                   * readers that have not yet drained from the queue.
                   */
                  return apparentlyFirstQueuedIsExclusive();
              }
          }
      

      It seems to me that the writer ("persistence-thread-p11-t4") has reached the head of queue, so the reader "default task-6" cannot continue (in order not to starve the writer). So the lock ("0x0000000719600070") locked by this this reader "default task-6" cannot be released, which caused the reader thread ("expiration-thread-p9-t1") cannot continue. So here a deadlock was formed.

      I here propose a way to avoid this deadlock by only using "storesMutex.writeLock().tryLock()" in "pollStoreAvailability".

      Also, Wildfly should provide a way to set "availabilityInterval".
