global stats key listeners incorrect after client got dropped from pending_tree for max_listeners
The global stats key
listeners is incorrect after a client is dropped from the
pending_tree as the mount is full. this happens on client move (as per admin request or fallback).
The code can be found looking in source.c for:
ICECAST_LOG_INFO("Client deleted, exceeding maximum listeners for this " "mountpoint (%s).", source->mount);
