CI? AttributeError: Something went wrong while opening shared memory.

[lanemeier7]

Hello, we are getting this error frequently but not always with our GitLab CI system when it runs pytest. This error does not seem to occur when running pytest manually on test computers or laptops.

Sometimes when test cases are run we see "Something went wrong while creating shared memory." error.

self = <catkit2.testbed.testbed_proxy.TestbedProxy object at 0x000001DDE7186CA8>
item = 'accufiz_interferometer'
    def __getattr__(self, item):
        '''Get the ServiceProxy named after the attribute.
    
        This acts as a shortcut for :func:`~catkit2.testbed.TestbedProxy.get_service`.
    
        Parameters
        ----------
        item : string
            The identifier for the service for which to return the ServiceProxy.
    
        Returns
        -------
        ServiceProxy or derived class object.
            A ServiceProxy for the named service.
        '''
        try:
            service = self.get_service(item)
    
            # Remember the service for next time.
            setattr(self, item, service)
    
            return service
        except Exception as e:
>           raise AttributeError(str(e))
E           AttributeError: Something went wrong while opening shared memory.
c:\catkit2\catkit2\testbed\testbed_proxy.py:66: AttributeError

Usually passes on retry.

It looks similar to this previously closed issue #113
