Thibaut commented on CASSANDRA-2543:
------------------------------------
You can close thisissue. I think it's a duplicate of CASSANDRA-2463 causing the
Garbage collector to run every few seconds.
I updated to 0.7.5 and everything runs much smoother (I have also seen no
timeoutexceptions in hector anymore).
> Node not responding, bringing down cluster, marked as up

> Key: CASSANDRA-2543
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2543
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.7.4
> Reporter: Thibaut
> Fix For: 0.7.6
>
> Attachments: jstack
>
>
> I have one node which constantly hangs and brings done the entire cluster
> (not giving any answers).
> If I restart the node, the node will hang after a certain number of time. I
> have no indication
> It's marked as up when executing the nodetool ring command.
> Executing the ring command on the node itself (without any traffic on the
> cluster) takes at least 2 minutes to execute. The node takes about 50%-100%
> of cpu over all cpus.
> Netstats doesn't list anything interesting:
> /software/cassandra/bin/nodetool -h localhost netstats
> Mode: Normal
> Not sending any streams.
> Not receiving any streams.
> Pool Name Active Pending Completed
> Commands n/a 0 51064
> Responses n/a 0 530479
> I attached the jstack of the node. There are no indications that the node has
> faulty hardware.
