I have multiple machines connected using RoSnodeJs ^3.0.4 version after Some days it got out a log message on ros container saying: couldn't resolve publisher host. Sometimes it continues communicating message between talker and listener but, sometimes it stopped the communication and the only way to get it back is restart the Master and talker and listeners. I already verified the env values as ROS_MASTER_URI, ROS_IP, also the ping between them are good it responses.

I'll appreciate your help guys! :D

"after some days it got out a log message"-- just to clarify, you're saying you've had this collection of javascript processes running for several days? And it sounds like restarting solves the problem?

Javascript programs are notorious for memory leaks, sounds like you have one.
