i had a stable ES cluster on aws ec2 instances till a week ago.. and i
don't know whats going on and my cluster keeps getting into a bad state
every few hours. the error says OOM but i know that that is not the reason.
the instance has enough heap space left. im running ES 0.90.6 version and
giving half the ram (8gb) to ES process. and i see these messages (the same
message kind of) in the logs on all the machines in the cluster.
[2014-02-11 03:17:39,936][WARN ][cluster.action.shard ] [Star-Dancer]
[facebook_022014] sending failed shard for [facebook_022014],
node[zO9Pc1GNSuiVMA_Kn2b3UQ], [R], s[STARTED], indexUUID
[qN3CUSfVS-m2KlgQQtOqxg], reason [engine failure, message
[OutOfMemoryError[unable to create new native thread]]]
any ideas on how to debug this or how to figure out whats causing this
would be really helpful.
