i’m trying to get fastcgi to work on solaris. my rails application works  
fine with normal cgi, but with fastcgi i always get a segmentationfault.  
the app runs normally with fastcgi under linux but that doesnt really  
help 🙂

tested systems:  
uname -a  
=\>  
SunOS … 5.10 Generic\_118833-17 sun4v sparc SUNW,Sun-Fire-T200  
or  
SunOS … 5.10 Generic sun4u sparc SUNW,Sun-Blade-100  
or  
SunOS … 5.10 Generic sun4u sparc SUNW,Sun-Fire-280R

i’ve tried several rubyversions with the same error (1.8.x), some  
selfcompiled with sun-compiler or gcc, some precompiled (blastwave).  
as httpserver i aim for apache 1.3 (included in oracle applicationserver  
with mod\_fastcgi), but tried apache 2.2 as well (with mod\_fcgid,  
selfcompiled).  
i followed several instructions on the net, eg

> **[Oracle Java Technologies | Oracle](https://www.oracle.com/java/technologies/)**
>
> Java can help reduce costs, drive innovation, & improve application services; the #1 programming language for IoT, enterprise architecture, and cloud computing.

i’ve also tried a simple test-application to rule out a problem in the  
rails application.

the actual errormessage looks like this:  
/usr/local/lib/ruby/1.8/timeout.rb:52: [BUG] Segmentation fault  
ruby 1.8.5 (2007-03-13) [sparc-solaris2.10]

[Mon Mar 19 08:41:58 2007] [error] [client 10.0.0.68] [ecid:  
1174290116:10.0.0.168:22842:0:15,0] FastCGI: incomplete headers (0 by  
tes) received from server “/public/dispatch.fcgi”  
[Mon Mar 19 08:41:58 2007] [warn] FastCGI: (dynamic) server  
“/public/dispatch.fcgi” (pid 22852) terminated due  
to uncaught signal ‘6’ (Abort), a core file may have been generated

the line in timeout.rb is Thread.start.  
at some times (other versions of ruby, gems etc…) i’ve got a  
segmentationfault in another rubyclass, also at a line with Thread.start

what else should i try? or does it look like a bug in ruby? i don’t  
really have the know-how to debug the coredump but if you think it to be  
rewarding, maybe i should consider trying…
