- Fixed incorrect init_connections() call in test_etcp_simple_traffic.c (was calling server_instance instead of client_instance) - Fixed double free in timeout_heap_pop() when handling deleted elements - Enhanced NULL pointer safety in uasync_print_resources() by removing complex heap manipulation - Added debug logging to timeout_heap_pop() for better error tracking Test results: test_etcp_simple_traffic now passes without double free errors
