-1 -> java.util.ArrayList.elementData(ArrayList.java:400) -> java.util.ArrayList.get(ArrayList.java:413) -> com.orientechnologies.orient.core.storage.impl.local.paginated.wal.OWriteAheadLog.flush(OWriteAheadLog.java:733) -> com.orientechnologies.orient.core.index.hashindex.local.cache.OWOWCache.flushPage(OWOWCache.java:1082) -> com.orientechnologies.orient.core.index.hashindex.local.cache.OWOWCache.access$1000(OWOWCache.java:67) -> com.orientechnologies.orient.core.index.hashindex.local.cache.OWOWCache$PeriodicFlushTask.iterateBySubRing(OWOWCache.java:291) -> com.orientechnologies.orient.core.index.hashindex.local.cache.OWOWCache$PeriodicFlushTask.flushRing(OWOWCache.java:254) -> com.orientechnologies.orient.core.index.hashindex.local.cache.OWOWCache$PeriodicFlushTask.run(OWOWCache.java:222) -> java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) -> java.util.concurrent.FutureTask.runAndReset(FutureTask.java:304) -> java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:178) -> java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:293) -> java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) -> java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) -> java.lang.Thread.run(Thread.java:744)Exception during data flush. nullException during data flush. null 2014-07-11 14:51:58:746 WARN Page in file observation.pcl with index 1684 was placed in wrong free list, this error will be fixed automatically.
