Hey Sharma, I didn't quite follow the timeline of events here or how the agent logs you posted fit into the timeline of events. Here's how I interpreted:
-Agent running fine with 0.24.1 -Transient ZK issues, slave flapping with zookeeper_init failure -ZK issue resolved -Most agents stop flapping and function correctly -Some agents continue flapping, but silent exit after printing the detector.cpp:481 log line. Is this accurate? What is the exit code from the silent exit?
