This commit addresses the issue where aggregators failed to connect to the server when running on different nodes. The changes include updates to `shm.py` and `channel_manager.py` to improve compatibility and error handling for multi-node setups. ### Changes in shm.py: - Refactored `LIFLSharedMemoryBackend` to dynamically support configuration of `sockmap_server_ip` and `rpc_server_ip` for non-localhost setups. - Enhanced shared memory cleanup logic to handle scenarios where segments may already be unlinked by another process. - Improved `_rx_task` logging to provide clearer debugging information during message reception and processing. - Added safeguards to ensure graceful handling of unexpected messages and connection issues. ### Changes in channel_manager.py: - Modified `_setup_backends` to correctly configure distinct backends for each channel, ensuring multi-node communication is supported. - Added logging for missing backends to help diagnose misconfigurations in `config.json`. - Enhanced default backend assignment logic to avoid conflicts when channels lack explicitly defined backends. ### Impact: - Fixes aggregator connection failures when running across multiple nodes. - Improves resilience and debuggability of shared memory operations and backend setups. - Ensures channel management adapts dynamically to different configurations. This commit has been tested with coord_hier_syncfl_mnist
