Subject [jira] [Commented] (AMQ-3906) repeated error message regarding chunk stream logged
Date Fri, 16 Nov 2012 11:22:12 GMT

    [ https://issues.apache.org/jira/browse/AMQ-3906?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13498740#comment-13498740
] 

Gary Tully commented on AMQ-3906:
---------------------------------

good news.
yeah, sorry about that startup issue. There has been a bunch of new modules introduced on
trunk so the snapshots are in a bit of flux... but that issue has been resolved. The snapshot
from last night (apache-activemq-5.8-20121116.041126-35-bin.tar.gz) should be fine.
