Hi List,
I'm running ES 1.0.1 in a 6 node configuration.
Some days ago we have experienced instability issues with our cluster.
At a certain moment no documents could be indexed anymore. After
restarting the indexing processes (Logstash), indexing worked again for a
short period of time only to stall again after a brief period.
The ES cluster had to be restarted to restore normal behavior. After that,
some (recent) index shards stayed unassigned.
I dropped the replication value for those indexes to 0 in order to clear
the unassigned shards. Enabling replication resulted again into
unassigned shards for the impacted indexes.
I have left the replication level to 0 for the troublesome indexes in order
to clear the cluster status.
Meanwhile, indexing and replication works again for any newly created
indexes.
What we noticed:
- The logs didn't reveal any immediate cause. The only reported issue
we saw in the logs prior to the incident is the below mentioned stack trace.
Afterwards, we have countered this issue by creating a template which
enforces the offending field to be treated as a string, which should
prevent the below mentioned error.
- Our ES collected metrics revealed a sudden drop of total number of
Java threads at the exact same moment.
My question: "Could the below mentioned stracktrace be the cause of any
cluster instability?"
Thanks,
Jelle
