Joey Ezekiel commented on FOP-2189:
-----------------------------------
Ok, I've upgraded to trunk and I believe that there are other functions
deprecated too. Is fopFactory.setUserConfig(); is no longer supported? and now
FopFactory.newInstance(new File(".").toURI()); has to be done?

> Key: FOP-2189
> URL: https://issues.apache.org/jira/browse/FOP-2189
> Project: Fop
> Issue Type: Bug
> Components: pdf
> Affects Versions: 1.0
> Environment: HP Unix
> Reporter: Joey Ezekiel
> Labels: Exception, Font", IOException, PDF, error
> Fix For: trunk
>
>
> 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 (errno:24))**
> 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?
