UPDATE: These seem to be some corrupted SSTable files. Since then I deleted them, and the instances of these messages are now much smaller. Thank you for your help!
About each launch of the Cassandra node, this appears in the logs several times before it is up and running ...
Fatal exception in thread Thread[SSTableBatchOpen:2,5,main] java.lang.AssertionError at org.apache.cassandra.io.sstable.SSTableReader.open(SSTableReader.java:150) at org.apache.cassandra.io.sstable.SSTableReader$1.run(SSTableReader.java:224) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662)
Can someone advise me on the best course of action to prevent this from future cases?
Thanks.
