Hi All,

I have following error on my Server which is working properly on my  
local on following line .

event\_id = MD5.new(“event-init-flash-#{Asteroid::now}”).to\_s #line 232

ERROR: wrong number of arguments (1 for 0)

I used shooting\_star to create an Chat Application.  
Ref:- [GitHub - genki/shooting-star: A practical comet server written by C/Ruby.](http://github.com/genki/shooting-star)  
Following are the REQUIREMENTS of the shooting\_star

- Linux or xBSD OS having epoll or kqueue.
- Increase ulimit of nofile up to over 100,000.  
(edit /etc/security/limits.conf file.)
- prototype.js 1.5.0+
- Ruby 1.8.5+
- Ruby on Rails 1.2.0+

My Local Configuration are  
O.S \>\> Linux  
Ruby \>\> ruby 1.8.6 (2009-08-04 patchlevel 383) [i386-linux]  
Rails \>\> 2.3.4  
shooting\_star \>\> 3.2.7  
prototype.js \>\> 1.6.0.3

My Server Configuration are  
O.S \>\> Linux  
Ruby \>\> ruby 1.8.6 (2009-08-04 patchlevel 383) [x86\_64-linux]  
Rails \>\> 2.3.4  
shooting\_star \>\> 3.2.7  
prototype.js \>\> 1.6.0.3

I just want to know what is the problem why it’s not working on server  
if everything is fine in local.

Regards,

Salil G.
