Subject [jira] [Commented] (AMQ-4888) Embedded broker requires 50GB of temporary space
Date Fri, 15 Nov 2013 11:07:22 GMT

    [ https://issues.apache.org/jira/browse/AMQ-4888?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13823562#comment-13823562
] 

Martin Lichtin commented on AMQ-4888:
-------------------------------------

Well, it's more that it issues an ERROR, but then somehow works anyway (should that message
rather be a WARN?).
And perhaps the default size of 50GB is a bit high.

I understand temp space may be used for swapping messages, perhaps I need to use VM cursor
to avoid potential disk use.

I also realize that when creating a Broker just with new BrokerService(), I have no idea how
its default configuration looks like.

> When starting an embedded broker via

>     broker.setPersistent(false);
>     broker.addConnector("tcp://127.0.0.1:61616");

> It issues an _ERROR_ saying:
> BrokerService                    | he.activemq.broker.BrokerService 1925 | 141 - org.apache.activemq.activemq-core
- 5.7.0 | Temporary Store limit is 51200 mb, whilst the temporary data directory: /path/paxexam/activemq-data/localhost/tmp_storage
only has 47743 mb of usable space
> Why would the broker require 50GB of temporary space?
