Subject [jira] Commented: (COCOON-2150) Error on resetting response
Date Wed, 12 Mar 2008 16:26:46 GMT

    [ https://issues.apache.org/jira/browse/COCOON-2150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12577905#action_12577905
] 

Grzegorz Kossakowski commented on COCOON-2150:
----------------------------------------------

@Joerg: See my response to Vadim who raised exactly the same concerns like some of you: http://article.gmane.org/gmane.text.xml.cocoon.devel/77006

I'll buffer only response if the response code has been set to 404 and will set sane default
(like 1MB) of a buffer to avoid OOMEs.  If you are generating more than 1MB response with
404 code then it's definitively a problem with your application and FATAL ERROR will be logged.

Does it sound fine?

> It seems to be thrown whenever the response object is reseted after the actual response
has been sent by the sitemap error handler. In this case reset is no longer possible since
the response has already been committed as stated in the error message.
