[Rails] segfault after page view

I realize this is slightly off-topic, but I''m stumped and I hope
someone
else has had the same problem.

When running a rails app using webrick (script/server), I can load any 
given page which involves a controller once, and any subsequent page 
loads trigger a "Segmentation fault" without any other info.

This problem is very new, and has only started occurring since I last 
updated my Gentoo linux system, so I assume it''s something to do with 
Gentoo, but the only place I see a problem is with rails.  In fact,
it''s
only with my personal projects; instiki works just fine (as do basic, 
html-loading webrick instances).

Go ahead and ask me any questions you think might be useful.  I have all 
kinds of details.  I wouldn''t ask this here if I had somewhere else to 
turn.

Thank you.

[Rails] segfault after page view

Try running memtest86.  The first thing I think when I start seeing
segfaults is bad RAM.

If that doesn''t show anything, I''d try recompiling ruby and
reinstalling
rails freshly.

[Rails] segfault after page view

Memory appears to be ok... I did try recompiling ruby (1.8.4-r1) and 
reinstalling the rails gem (as well as activerecord, actionpack, 
actionmailer, actionwebservice, activesupport).  No effect.

What''s odd is that everything works fine on the first page request, so 
if I keep stopping and restarting webrick, then I can use the 
application.  If anyone''s interested in an strace, I have that too. Any
other ideas?

[Rails] segfault after page view

As an interesting side note, it''s not just webrick, mongrel also 
segfaults in precisely the same way.  The bizarreness of this problem is 
painful.

That tells me it''s probably not the webserver then.

Are you require''ing any 3rd party packages?  Are any of them C
extensions?  If so, which ones?

BTW, which version of Ruby?  Is it 32 or 64 bit?

Dan

I have a similar problem that only seems to effect Hieraki but not  
any of the rails apps that I am writing.  During a callback from  
doing an insert into the user table, the ruby interpreter seg- 
faults.  It is in the middle of the Activerecord base class.  It is  
trying to invoke create_or_update (if I remember correctly) and it  
appears to try to start executing code in the middle of the method,  
not the beginning.  At this point, it is in ruby code but it has been  
calling into the C routines that interface into MySQL.  I am running  
Ruby 1.8.4, Rails 1.0.0, MySQL 4.1.18, and the MySQL 2.7 ruby  
interface routines.  All this is running on FreeBSD 5.4. I have tried  
compiling everything from scratch.  I have tried running Hieraki as a  
cgi, fast-cgi and scgi process using Apache 2.0.55.  I have also  
tried running it using Webrick.  I have tried running it on another  
machine, using the same OS and software versions.  I have also tried  
running it with PostgreSQL 8.1.2 using the C interface version  
0.7.1.  It always seems to seg-fault in the same place.

I haven''t had any more time to pursue the problem in the last few  
weeks and unfortunately, I won''t have time to look into it any  
further for a few weeks.

[Rails] segfault after page view

How long have you been running this gentoo install? Is it fairly new?

Are you sure your CFLAGS and MARCH or MCPU are set correctly in make.conf? What
arch are
you running?

Did you update GCC recently? If so, was it the 3.3.* to 3.4.* jump, cuz that
required an
upgrade to libtool and the installation of a libstdc++ compat library?

Did you use the rails/ruby packages from portage? Did you use masked versions?

Did you check gentoo''s bugzilla for any reports of segfaults in
ruby/rails/etc?

What exactly was that last update you did? Rails/Ruby weren''t part of
that upgrade right?

[Rails] segfault after page view

The gentoo install is 2005.1 and I installed it about 4 months ago. 
There have never been any problems with ruby until this last emerge. 
The architecture is ~x86 and I doubt there''s anything wrong with my 
make.conf settings, as those haven''t changed.

At the bottom of this message is a list of all the packages I emerged 
when this became a problem.  I use ruby and rubygems from portage, but I 
use rails and associated packages from gems.  I''m using ruby-1.8.4-r1 
and rubygems-0.8.11.  Neither are masked. (I have also tried 
rubygems-0.8.11-r3).

I was loading ruby-mysql, but I have since disabled activerecord, and 
there been no change in the problem.

I have searched the Gentoo bugzilla for a ruby or rails problem like 
mine, but have not found any help.  I''m submitting my problem there too
in hopes of an answer.

Packages emerged:
sys-apps/sed-4.1.4-r1

[Rails] segfault after page view

Crap. I was hoping that my questions would shake loose a solution from another
quarter...
I''m kind of out of ideas. I don''t see anything in that emerge
list that would cause
problems with ruby... although, I''m no expert on linux library
dependencies.

What seems really weird about this is that third party rails apps still work
fine but your
code breaks. Are you doing anything "crazy" in your code? I have no
idea what "crazy"
might look like, but I guess anything that''s not like typical rails
coding.

You could also try to narrow down where the segfault is occuring with
breakpoints or log
statements. Maybe some piece of Ruby was installed outside of portage at some
point and is
still around, and somehow your code is going off into that old code... where
things aren''t
arranged in memory quite the way they should be.

As you can probably guess I''m kind of whiffing in the breeze here... I
don''t have any
solid ideas, just trying to give you some avenues of exploration.

Oh, and someone else was talking about suspecting memory when they get
segfaults, but I''ve
never thought that. Having done a little beginning programming in C,
I''m all too familiar
with how easy it is to segfault: just mess up where your pointers are pointing
and your
there! (Did that over and over and over... :-) )

good luck!

[Rails] segfault after page view

I struggled with segfaults for about a month.  The only thing that fixed
mine was:

gem uninstall mysql

I then dowloaded the latest ruby mysql bindings off the web and used
those.  If you already disabled active record this probably won''t help
but thought I would mention it anyways.

[Rails] segfault after page view

I''ve actually encountered some of this on Windows recently, under
WEBrick and Mongrel.
I''m still trying to isolate a test case, sadly.

Here''s an example of what I''m seeing:
http://localhost:3000/plans/show/9937 -> /plans/list_by_be/2006/01/60910301
./script/../config/../vendor/rails/activerecord/lib/active_record/associations.rb:729:
[BUG] Segmentation fault
ruby 1.8.4 (2005-12-24) [i386-mswin32]


This application has requested the Runtime to terminate it in an unusual way.
Please contact the application''s support team for more information.

I don''t have MySQL installed; I only use Postgres and Oracle.
