Subject [jira] [Commented] (FOP-2189) Apache FOP 1.0 Multithreading Problems - Too many open files err24
Date Mon, 10 Jun 2013 06:39:19 GMT

    [ https://issues.apache.org/jira/browse/FOP-2189?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13679338#comment-13679338

Joey Ezekiel commented on FOP-2189:

The limit is currently 4096 which is the process limit and in normal circumstances I do not
think that the no of files opened concurrently should exceed that limit. I will try and replicate
this on a windows environment.

> We use Apache FOP to convert a whole lot of XML's to AFP's and PDF's. Our current load
would be around 25k files per run on a HP-UX system. We have 12 threads in total that are
used to initialize and trigger the FOP conversion in a producer-consumer fashion. Recently
there have been multiple failures during conversion and when looked up, we've received generic
FOP errors like:
> **ERROR,2460364,FOToPDF_Thread_11,FOP Exception, something.pdf,Failed to resolve font
with embed-url './Fonts/arial.ttf'**
> or its an error failing to load the font metrics file although the files are intact with
the right permissions. Many other PDF's are generated so this can't be the problem.
> We also wind up with:
> **java.io.FileNotFoundException: /PDF/20130111130002/something.pdf (Too many open files
> judging by the logs and volume being processed, this looks like an FOP problem. I've
read that FOP has had this issue in the past with the font files. There have been instances
where Apache has opened each font file multiple times and not closed the handles resulting
in a large number of open files. This was supposed to be fixed, but if it still persists,
what would be a good and quick solution to this?
