ImageMagick thread problem on startup

[ajsinclair]

I have just installed Alfresco and despite a few minor issues everything seems to be OK except that ImageMagick is reporting an error on startup.

02:59:05,843 ERROR [transform.magick.AbstractImageMagickContentTransformer] ImageMagickContentTransformer not available: unable to create new native thread
‍‍

ImageMagick is installed and convert is available on my system path and seems to work fine on it's own.

# convert –version
Version: ImageMagick 6.2.8 03/14/07 Q16 file:/usr/share/ImageMagick-6.2.8/doc/index.html
Copyright: Copyright (C) 1999-2006 ImageMagick Studio LLC‍‍‍

Can anyone assist?

Can you set logging for org.alfresco.repo.content.transform.magick.AbstractImageMagickContentTransformer to debug?  That class is throwing an exception when it tries to invoke the ImageMagick binary, but all we're seeing at the moment is the message from that exception: "unable to create new native thread" - seeing some more details from the exception should help with troubleshooting.

From a quick google, it looks like the following post might be relevant: http://www.talkingtree.com/blog/index.cfm/2005/3/11/NewNativeThread too.

Cheers,
