Mongrel segfaults

Ruby Apps Ferret
1

I have seen several threads here and elsewhere about ferret and/or aaf
causing seemingly random segfaults in mongrel. However, I didn’t see in
any of these threads if a resolution was ever offered.

I am currently experiencing this problem and I am keen to get a
solution. I appreciate any update that anyone can give me.

Best Regards,

Danny

A bit more information would possibly help :wink: i.e. platform, index
size, using DRb or not, …

Don’t you get any information about where the error happened? You could
also try doing a ‘killall -USR1 mongrel_rails’ to let mongrel issue more
debug information.

Platform is OS X 10.4.9, not using DRb. This is happening in
development mode, with trivially-sized indexes. In fact, I just
reproduced it with no index (that is, before the index had been built).
We have only one aaf model, and we do disable_ferret(:always) from a
before_save filter, and update the index manually from a cron job. The
crash I just reproduced happened before the index had ever been updated.

Thanks, didn’t realize I could do that. Here is what I get on stderr-

/opt/local/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/core_ext/module/inclusion.rb:4:
[BUG] Bus Error
ruby 1.8.4 (2005-12-24) [powerpc-darwin8.6.0]

Doesn’t seem like there’s much there.

Strange. And that did happen without doing a search or update?

Correct. This happened just doing a page load that had nothing to do
with search or update.

You could checkout the Ferret source and run Ferret’s test suite, just
to make sure there’s nothing really broken.

Hmmm- good idea. I’ll try it today and post here if I find anything.
In the meantime, I have seen other reports of this bug on OS x- no one
has been able to find out why this happens on OS X only?

Best Regards,

Danny
