Resolution:
Wont fix
Affected version:
2.0.3

Description

Platform:
Redmine 2.0.3
jRuby 1.6.7, rails 3.2.6
gem 1.8.24
Tomcat 6.0.29
java 1.6.0_31 (HotSpot) 64-bit under Linux CentOS release 5.5 (Final)

I have built the war file from sources with Warbler 1.3.6 and we don't use specific JVM args for jRuby.

Description:
When two or more users access the same wiki page, http threads become (dead) locked. When all ruby runtimes are locked, Redmine, does not respond any more. The problem is not systematic but frequent and quite easy to reproduce. It seems that wiki pages containing images are more likely to produce the bug. This is a blocking bug since we must restart TOMCAT several times per day.

I have recorded thread dumps to provide you some insights. I am not a ruby developer so I cannot easily interpret them. I have sent also you our web.xml file. We are using org.jruby.rack.RackServlet instead of the filter otherwise we cannot use Redmine integration with Eclipse MyLyn.

Note that everything is OK with Redmine 1.4.4. I have also upgraded to jRuby 1.7.0.preview2 => redmine 2.0.3 still have the problem and Redmine 1.4.4 is still OK.

sincerly
Vincent
