Re: [etch-users] repeated crashes due to segmentation fault

[Jason H. <jh...@ap...>]

Are you running with the libxml gem?  That's the default if you have the libxml or libxml-ruby gems installed.

If so try installing the nokogiri gem and set "xmllib=nokogiri" in your environment before starting up mongrel.  Those seg fault crashes are always the libxml gem in my experience.  Using nokogiri for XML parsing will be the default starting in the next etch release.  Nokogiri is newer but seems much better written and tested than the libxml gem.  I and at least one other user on the list have switched our installations to nokogiri and eliminated the seg faults.
