Podman stopped working after too many connections was opened (All pipe instances are busy) #23392

Issue Description

We have several components with unit tests which needs a (Kafka) container for execution. When we execute the unit tests for the components sequentially, every thing is fine. But when we execute the unit tests for the different components parallel, the tests stop working after some time and from that point on all remaining tests gets a timeout when they try to connect to the container. Afterwards it is possible to stop the container and start a new one, but also to the new container the connection is no more possible (timeout). After a restart of podman machine following error occurs:

podman machine start
Starting machine "podman-machine-default"
API forwarding for Docker API clients is not available due to the following startup failures.
        CreateFile \\.\pipe\docker_engine: All pipe instances are busy.

Podman clients are still able to connect.
Error: machine did not transition into running state: ssh error: ssh: handshake failed: read tcp [::1]:60755->[::1]:65395: wsarecv: An existing connection was forcibly closed by the remote host.

Another colleague who is using docker is able to execute the tests.

Steps to reproduce the issue

Steps to reproduce the issue:

  1. Start a container.
  2. Send multiple request in parallel to this container until they run in timeout. (Unfortunately I cannot tell how many request are send in parallel.)
  3. Restart the podman machine

Describe the results you received

See issue description

Describe the results you expected

  1. I expect that podman can handle multiple request in parallel and not only sequential processing.
  2. I expect that the same tests which are executable with docker are executable with podman.

podman info output

podman version (after the test execution):
Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM
Error: unable to connect to Podman socket: failed to connect: ssh: handshake failed: read tcp 127.0.0.1:60786->127.0.0.1:65395: wsarecv: An existing connection was forcibly closed by the remote host.
