Hi,

I have a ruby on rails website. Server configuration is:

1. Nginx
2. 4 mongrel clusters running on different ports.

After a long idle time few of the mongrel clusters stops responding. I  
have set “ActiveRecord::Base.verification\_timeout = 14400” in  
environment.rb file, but still it’s not working.

On executing “lsof -i -P | grep CLOSE\_WAIT” command, I usually get a  
long list of mongrel\_clusters.

Please let me know if you have any solution for this problem.

Thanks in advance.
