Problem of program run error during loop the open and close

[fkdlqj13245]

Describe what you want to implement and what the issue & the steps to reproduce it are:

It has the error during the program run( it happened close with the ulimit open files umber).
The device is not reachable or controlled by another application.

Code

    while True:
    idx += 1
    print('\nopen: ', idx)

    # open
    try:
        camera.Open()
    except Exception as e:
        print('[ERROR]: {0}'.format(traceback.format_exc()))
        break

    gc.collect()

    print('sys.getrefcount(instance):', sys.getrefcount(instance))
    print('sys.getrefcount(device):', sys.getrefcount(device))
    print('sys.getrefcount(camera):', sys.getrefcount(camera))

    # close
    camera.StopGrabbing()
    camera.Close()

    sleep(1)#sleep(10)

    print('closed')

# close
camera.StopGrabbing()
camera.Close()

This could be bug in GigE TL. you can build pypylon against pylon 7.0 or I can build a wheel if you let me your python version

Is the happened only pylon 7.4.0?
Here is the python version.
PYTHON: 3.8.10

[Is the happened only pylon 7.4.0?] yes. would you build your version against 7.0?
