Steps to reproduce issue

1. launch nodes
2. ros2 param list
3. ros2 param dump NODE_NAME

Expected behavior

1. param list gives us a list of commands
2. param dump gives us the parameters of a certain node

Actual behavior

1. param list hangs forever
2. param dump gives us the parameters of a certain node

Additional information

I tried to source a humble environment for ROS2 param list, it gave me a list of params, though it triggered a hash issue because Humble did not implement hash as expected.

@makeecat thanks for creating issue.

would mind trying ros2 param list --no-daemon when you meet this problem to see if that can print the expected result. if it does, the problem is related to the ros2daemon.
and it would be probably helpful if you share the complete procedure to make this problem happen. with my local environment, this problem cannot be observed.

When I tried to use ros2 param list --no-daemon, it hang as well

[Kaju-Bubanja]

I have the same issue on humble built by source on following commit of ros2cli:

commit fb71227
Author: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com>
Date: Sat Jul 19 21:45:09 2025 -0700

I tried ros2 param list --no-daemon and it hangs as well

I deleted build/install/log and rebuilt everything and still experience the issue.

I can't run ros2 docter --report it also hangs...

Ok, some debugging led me to the C++ implementation, where I'm currently at. I will show you my current progress and this might help somebody else figure out what's going on.

1. ros2 param list gets stuck in the exit method of the NodeStrategy:

    def main(self, *, args):  # noqa: D102
        with NodeStrategy(args) as node: <----------------- times out in the constructor and with that patched gets stuck in the __exit__ method
            node_names = get_node_names(
                node=node, include_hidden_nodes=args.include_hidden_nodes)
        node_name = get_absolute_node_name(args.node_name)

2. The xmlrpc server proxy under http://127.0.0.1:11511/ros2cli/ times out and I had to add TimeoutError to be able to debug further:

class NodeStrategy:

    def __init__(self, args, *, node_name: Optional[str] = None):
        use_daemon = not getattr(args, 'no_daemon', False)
        if use_daemon and is_daemon_running(args):  <------------- is_daemon_running times out

3. The connected attritube times out:

def is_daemon_running(args):
    """
    Check if the daemon node is running.

    :param args: `DaemonNode` arguments namespace.
    """
    with DaemonNode(args) as node:
        return node.connected <----------- times out

4. self._proxy.system.listMethods() times out, I patched it by adding TimeoutError to the Exceptions that are being caught. Might this be a fix that is needed in general?

class DaemonNode:

    def __init__(self, args):
        self._args = args
        self._proxy = ServerProxy(
            daemon.get_xmlrpc_server_url(),
            allow_none=True)
        self._methods = []

    @property
    def connected(self):
        try:
            self._methods = []
            for method in self._proxy.system.listMethods(): <---------------- times out
                if not method.startswith('system.'):
                    self._methods.append(method)
        except (ConnectionRefusedError, ConnectionResetError, TimeoutError):
            return False
        return True

5. I have only following node names returned by node_names = get_node_names(node=node, include_hidden_nodes=args.include_hidden_nodes), namely: [('_ros2cli_1000432', '/')]
6. Then the NodeStrategy hangs in the __exit__ method

class NodeStrategy:
    ....
    def __exit__(self, exc_type, exc_value, traceback):
        self._in_scope = False
        if self._direct_node:
            self._direct_node.__exit__(exc_type, exc_value, traceback) <---------- hangs here
        if self._daemon_node:
            self._daemon_node.__exit__(exc_type, exc_value, traceback)

7. Then the DirectNode hangs in the __exit__ method:

class DirectNode:
    ...
    def __exit__(self, exc_type, exc_value, traceback):
        self.node.destroy_node() <------------ hangs here
        rclpy.try_shutdown()

8. Then the Node hangs in the destroy_node method:

class Node:
    ...
    def destroy_node(self):
        """
        Destroy the node.

        Frees resources used by the node, including any entities created by the following methods:

        * :func:`create_publisher`
        * :func:`create_subscription`
        * :func:`create_client`
        * :func:`create_service`
        * :func:`create_timer`
        * :func:`create_guard_condition`

        """
        # Drop extra reference to parameter event publisher.
        # It will be destroyed with other publishers below.
        self._parameter_event_publisher = None

        # Destroy dependent items eagerly to work around a possible hang
        # https://github.com/ros2/build_cop/issues/248
        while self._publishers:
            self.destroy_publisher(self._publishers[0])
        while self._subscriptions:
            self.destroy_subscription(self._subscriptions[0])
        while self._clients:
            self.destroy_client(self._clients[0])
        while self._services:
            self.destroy_service(self._services[0])
        while self._timers:
            self.destroy_timer(self._timers[0])
        while self._guards:
            self.destroy_guard_condition(self._guards[0])
        self.__node.destroy_when_not_in_use() <------------------- hangs here
        self._wake_executor()

9. Which leads us to the C++ destroyable.cpp and this is where I am currently. I don't know the C++ code from rclpy well, but I will dig in, but maybe somebody else who know the code better has an idea what could be causing this, especially since it seems like the freeze happens in the [('_ros2cli_1000432', '/')] node

[fujitatomoya]

@Kaju-Bubanja thank you for digging this issue!

i do think so. can you create the PR? i am happy to review this PR.

rclpy::LoggingGuard, it really looks suspicious for this issue... 🤔

https://github.com/ros2/rclpy/blob/06144929b76b916a0c370b9ba0e1aa52c8758842/rclpy/src/rclpy/node.cpp#L473

if you can reproduce this issue, can you remove the above single line to see if the problem still can be observed?

[Kaju-Bubanja]

@fujitatomoya Yes, easy PR: #1092

Related to that MR, is it normal for the ProxyServer to Timeout? Something is listening on the url

$ ss -ltnp | grep 11511 || lsof -iTCP:11511 -sTCP:LISTEN                            [9:21:23]

but nc and curl hang:

$ nc -vz 127.0.0.1 11511                                                            [9:23:19]

*   Trying 127.0.0.1:11511...
^C

I can 100% reproduce the issue, it happens every time i run ros2 param list and is persistent across reboots. I tried removing that line, recompiled:

$ colcon build --symlink-install --cmake-args --packages-select rclpy              [13:05:45]
Starting >>> rclpy   
--- stderr: rclpy                               
lto-wrapper: warning: using serial compilation of 3 LTRANS jobs
---
Finished <<< rclpy [22.0s]

Summary: 1 package finished [24.5s]
  1 package had stderr output: rclpy

but still get the same hang on the call to self.__node.destroy_when_not_in_use()

[Kaju-Bubanja]

Ok, I think it is related to ROS_DOMAIN_IDs, since when I set my domain ID to 1, where all the nodes run everything works as normal, but when I leave it the default value, by not setting anything, which I assume is 0, then I get the freezes

[fujitatomoya]

ROS_DOMAIN_ID is just a offset for multicast to isolate the logical discovery range.

can you try the following if the problem still happens with default ROS_DOMAIN_ID?

1. reproduce the freeze problem
2. issue ros2 daemon stop to stop the ros2daemon process that listens on the XMLRPC server port.
3. issue ros2 daemon start to restart the ros2daemon process.
4. see if the problem still stays.

[Kaju-Bubanja]

Yeah, the ROS_DOMAIN_IDs thing might have been a red herring. Anyways I can't run ros2 daemon stop, since it hangs...
It is the first thing it says to try in other issues, but nothing but a reboot fixes the problem

[Kaju-Bubanja]

Ok, more clues, I have a .bashrc with: export RMW_IMPLEMENTATION=rmw_fastrtps_cpp but used zsh with export RMW_IMPLEMENTATION=rmw_cyclonedds_cpp and that somehow bricked the proxyserver, even after setting the RMW_IMPLEMENTATION to rmw_fastrtps_cpp like the other nodes which are started at system boot the shell was somehow dead. But now after a reboot and RMW_IMPLEMENTATION correctly set to export RMW_IMPLEMENTATION=rmw_fastrtps_cpp things work again
