Subject [jira] [Commented] (TIKA-2802) Out of memory issues when extracting large files (pst)
Date Thu, 16 May 2019 06:04:01 GMT

    [ https://issues.apache.org/jira/browse/TIKA-2802?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16841008#comment-16841008

Andreas Hubold commented on TIKA-2802:
--------------------------------------

I wonder if the addition of Xerces is still  recommended for Java 9+ projects. 

Since Java 9, the JDK contains bugfixes from Xerces 2.11.0, see  lhttps://bugs.openjdk.java.net/browse/JDK-8044086
For Java 13, an update to Xerces 2.12.0 is in progress according to https://bugs.openjdk.java.net/browse/JDK-8214064

Do you know which Xerces issue was causing the problem?

> I have an application that extracts text from multiple files on a file share. I've been
running into issues with the application running out of memory (~26g dedicated to the heap).
> I found in the heap dumps there is a "fDTDDecl" buffer which is creating very large char
arrays and never releasing that memory. In the picture you can see the heap dump with 4 SAXParsers
holding onto a large chunk of memory. The fourth one is expanded to show it is all being held
by the "fDTDDecl" field. This dump is from a scaled down execution (not a 26g heap).
> It looks like that DTD field should never be that large, I'm wondering if this is a bug
with xerces instead? I can easily reproduce the issue by attempting to extract text from large
.pst files.
