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.
