We have a cluster APM setup with total of 20 Agents customized/configured in loadbalancing.xml to connect one collector. Hope worked fine for 10 days after we did the changes in loadbalancing.xml file.
1) Frequent disconnecting all agents.

I request anybody please suggest few valuable inputs.
PFA for Log files from MOM Enterprise Manager and Collector.
Swift response are highly appreciated.
