Redmine 2.4.5 stops frequently by showing "No route to host - connect(2) (Errno::EHOSTUNREACH)", Help required.
As mentioned in the subject line, i am using Redmine 2.4.5 in ruby 1.9.3 and passenger 4.0.48.
I am recently started to get "No route to host - connect(2) (Errno::EHOSTUNREACH)" error message in Passenger logs after Redmine being stopped automatically.
Now, i am completely not able to start Redmine via Passenger as it would refuse to start with that error message.
Now i am using Redmine over Webrick by restarting Webrick often, as it would also stop within a little time with no errors as i do not know where can i find the Webrick logs.
We are using multiple versions Redmine in our server without any problem, but we have facing so much problem recently in this specific installation redmine.
All instance of Redmine uses distinct port numbers and i have changed port number of this instance to different numbers multiple times and didn't find any noticeable improvement.
Please help me to resolve this issue soon, as i am getting pressure from my teams.

I was able to resolve the issue finally.
The culprit was malformed firewall rules.
