javax.management.InstanceAlreadyExistsException: during startup ---------------------------------------------------------------
Key: CASSANDRA-3217 URL: https://issues.apache.org/jira/browse/CASSANDRA-3217 Project: Cassandra Issue Type: Bug Reporter: Thibaut Priority: Minor Hi, I got this error on one machines after restarting (the node could have been killed due to an outofmemory error). It would crash on each restart on this error. I copied over the system table from another machine and deleted the locationinfo files and everything worked fine. I also had to delete 2 db files which coulnd't be loaded due to UTF-8 encoding errors. These rows were from the same table_feedfetch. The node might have memory errors, I'm going to check this. So it might be related to that.
