Below is my configuration:

  • mCollective client 2.5.2, erlang-R16B03-0.2, rabbitmq server 3.3.4 installed on RHEL 6.4

  • mCollective server 2.5.2 (with stomp rubygem 1.3.2 and ruby 1.8.7) installed on RHEL 5.10 (on multiple hosts which are in a different data center than the host running MC client)

mco ping shows all mCollective servers in the results for a while. But If I run any agents (plugins) across the fleet, some hosts stop responding to the mco ping any longer. I see the message below in mCollective server.log only on the hosts which are missing. Other hosts dont have this message.

  W, [2015-10-15T20:56:39.968701 #29827]  WARN -- : agents.rb:136:in `dispatch' Timeout while       handling message for <agent name>

I tried increasing the timeout values in the below files and restarted mCollective, but it didnt help.

  • mcollective/agent/discovery.rb

  • mcollective/discovery/mc.ddl

Also added the plugin.discovery.timeout parameter to server.cfg and client.cfg, but to no avail.

Can anyone please suggest a solution? Thank you

does increasing timeout on commandline work ( e.g. -t 15)

Thanks for responding. No, increasing timeout is not helping.

Also, different kinds of messages are being displayed in rabbit@<rabbitmq server="">.log on the broker. Two of them below:
