hi Ashwini S.. I am not sure if the rabbitmq snaps have this capability. you may file an enhancement request for this. But JMS snaps has this feature. you can directly enter the failover url in the JNDI props of the JMS account. Let me know if this helps.
Seems u r running the pipeline on a linux plex. If yes then we use named pipes to write to temp file. there is a possibility some disturbance may have occurred. Can you just try to re-run the pipeline, and see if it works?
