Facing issue with Ruby XMPP4r gem

Hi,

I am facing a weird issue with XMPP4r i.e. it gets stuck with a specific code. I am able to recreate the problem with the following snippet which loops through all the users in the system and tries to connect to the XMPP server:

def connect_users_to_chat

  User.all.each do | user |

    begin

      chat_username = user.try(:chat_username)

      client = Jabber::Client.new(Jabber::JID::new("#{chat_username}@localhost"))

      client.allow_tls = false

      client.connect

      puts "#{chat_username} connected"

      client.auth('password')

      puts "#{chat_username} authorised"

      client.close

    rescue Exception => ex

      puts "Exception while connecting for #{chat_username} with id #{user.id} with msg #{ex.message}"

    end

  end

end

 

I ran it against 10-12 users and the code gets stuck while calling auth method. Its purely random i.e. am not able to reproduce it for a specific user or specific position.

When I did a strace on the process, it showed the status as FUTEX_WAIT_PRIVATE.

Any clue on whats wrong and how to tackle it?

Thanks,

Leena
