Subject [jira] [Commented] (CASSANDRA-7724) Native-Transport threads get stuck in StorageProxy.preparePaxos with no one making progress
Date Mon, 15 Sep 2014 07:20:33 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7724?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14133646#comment-14133646
] 

Anton Lebedevich commented on CASSANDRA-7724:
---------------------------------------------

That was a single node so at least one of them should have been moving forward. 
But thread dump is not expected to show all threads at the same point in time exactly so it
could have missed that single making progress thread. I dumped threads several times with
the same results (all threads waiting).

> We've got a lot of write timeouts (cas) when running 
> "INSERT INTO cas_demo(pri_id, sec_id, flag, something) VALUES(?, ?, ?, ?) IF NOT EXISTS"
>  from 16 connections in parallel using the same pri_id and different sec_id.
> Doing the same from 4 connections in parallel works ok.
> All configuration values are at their default values.
> CREATE TABLE cas_demo (
>   pri_id varchar,
>   sec_id varchar,
>   flag boolean,
>   something set<varchar>,
>   PRIMARY KEY (pri_id, sec_id)
> );
> CREATE INDEX cas_demo_flag ON cas_demo(flag);
> Full thread dump is attached.
