Richard Low commented on CASSANDRA-7144:
----------------------------------------
We saw this in 3 separate clusters at roughly the same time. In 2 clusters it
happened on one node only. On 1 cluster it happened on 3 nodes.
Every time it happened, there were 3 errors in WRITE threads with stack trace:
{code}
java.lang.AssertionError
at
org.apache.cassandra.db.RowMutation$RowMutationSerializer.serialize(RowMutation.java:271)
at
org.apache.cassandra.db.RowMutation$RowMutationSerializer.serialize(RowMutation.java:259)
at org.apache.cassandra.net.MessageOut.serialize(MessageOut.java:120)
at
org.apache.cassandra.net.OutboundTcpConnection.writeInternal(OutboundTcpConnection.java:251)
at
org.apache.cassandra.net.OutboundTcpConnection.writeConnected(OutboundTcpConnection.java:203)
at
org.apache.cassandra.net.OutboundTcpConnection.run(OutboundTcpConnection.java:151)
{code}
and the IPs in the thread names are all adjacent in the ring (we have
replication 3+3 in 2 DCs). 2-3 seconds following that, there are then stack
traces in the MutationStage like:
{code}
java.lang.AssertionError

org.apache.cassandra.service.StorageProxy$6.runMayThrow(StorageProxy.java:870)
at
org.apache.cassandra.service.StorageProxy$HintRunnable.run(StorageProxy.java:1961)
{code}
The number of these varies from 5 to 65.

> Key: CASSANDRA-7144
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7144
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: Ubuntu 12.04 w/ Oracle JVM, 5 nodes cluster. Nodes 2GB /
> 2 Cores in DigitalOcean.
> Reporter: Maxime Lamothe-Brassard
> Assignee: Tyler Hobbs

> First time reporting a bug here, apologies if I'm not posting it in the right
> space.
> At what seems like random interval, on random nodes in random situations I
> will get the following exception. After this the hinted handoff start timing
> out and the node stops participating in the cluster.
> I started seeing these after switching to the Cassandra Python-Driver from
> the Python-CQL driver.
