Thibaut commented on CASSANDRA-2543:
------------------------------------
I stopped all java programs and restarted the cluster and increased the heap
size to 5.5 gig. All my table have a memtable limit of 32MB and I only have
about 20 tables with 2 column families in each table.
Executing a manual compactation or just waiting will return the following error:
ERROR [ReadStage:24] 2011-04-22 19:30:58,330 AbstractCassandraDaemon.java (line

One table has 778 intermediate tables and won't compact. (Each table has about
the size of the memtable flush limit). Only the first one are biggers (e.g 5x
19 GB)

It's certainly something related to compacting.
There are log file entries related to cassandra compacting other tables
(Compacting table_....). But this table never shows up (even not when I trigger
a manual compaction on that table).

> 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.
