[ruby-core:26886] [Bug #2295] segmentation faults

From: Jarred Nicholls <redmine@...>
Date: 2009-11-24 01:53:09 UTC
List: ruby-core #26886
Issue #2295 has been updated by Jarred Nicholls.


tomer,

I ran into seg faults on my EC2 boxes with 1.9.1 as well.  If your issue is that same as mine, you need to change your kernel and ramdisk for your EC2 instance from the default (which I believe is 2.6.21) to a different version (i.e., 2.6.18).  Amazon is doing updates to fix their 2.6.21 and their Ubuntu Server 2.6.31 (beta) kernel.  But, if you load the 2.6.18 kernel and associated ramdisk, you might not have those problems anymore.  However, my issue literally crashed the kernel/instance and forced a reboot of the instance.  But, you can at least give it a shot.

Kernel ID: aki-f5c1219c
Ramdisk ID: ari-dbc121b2

I wish you luck.  For me, I simply went back to using Passenger with Ruby EE (which is 1.8.7), and did a patch to the Passenger gem to do asynchronous request dispatching to allow for long running I/O requests to run in parallel so they wouldn't block short quick requests from getting through.  I'll move to 1.9 when everything is more stable, and/or go to JRuby if I need true & fast multi-threading.  I tried JRuby and was having issues with Cookie Store and decided its memory footprint was way too big for the time being.
