Hi,
I have a 4 cluster version 1.0.3 which was upgraded from 0.7.6 in 2 stages. Upgrade to 1.0.0 run scrub on all nodes Upgrade to 1.0.3 I keep getting this errors from time to time on all 4 nodes. Is there any maintenance I can do to fix the problem? I tried to run repair on the cluster a few times but it did not help. Thanks in advance for your help. Michael The kind of errors I get: NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 AbstractCassandraDaemon.java (line 133) Fatal exception in thread Thread NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 java.lang.AssertionError NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 at org.apache.cassandra.service.GCInspector.logGCResults(GCInspector.java:103) NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 at org.apache.cassandra.service.GCInspector.access$000(GCInspector.java:41) NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 at org.apache.cassandra.service.GCInspector$1.run(GCInspector.java:85) NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 at java.util.concurrent.FutureTask$Sync.innerRunAndReset(FutureTask.java:317) NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:150) NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$ 101(ScheduledThreadPoolExecutor.java:98) NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.runPeri odic(ScheduledThreadPoolExecutor.java:181) NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(Sch eduledThreadPoolExecutor.java:205) NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.ja va:886) NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:9 08) NYC-Cass3 ERROR [ScheduledTasks:1] 2012-01-03 05:54:16,392 at java.lang.Thread.run(Thread.java:619)
