RemotingException - Object has been disconnected or does not exist at the server

Question

I am loading a dll into multiple AppDomains at the same time, but sometimes this error occurs

2018-03-12 16:38:47:377 SYS [Service] ExecutionManager(UpdateRunningEntries)(262) It was not possible to get the correct status for ProjectKeyFigures. Exception.Message: "Object '/90fe8696_0151_4ecb_8a5f_981be336df24/y67px9b26wwflgpukicaxrdv_6545.rem' has been disconnected or does not exist at the server."

I am requesting the Status property at least 4 times a minute, but as you can see this is not enough, as the Exception still occurs

Will it help to raise the amount of reads?
Or does it not refresh the Lease-time, if I read on a Property?

And if it does not, do I then have to set the InitializeLifetimeService to return null, or can I somehow renew the LeaseTime in the dll?

The object I am calling in the dll is MarshalByRefObject and have an interface, where e.g. the Status property is defined.
The Status property is a model with a StatusEnum and a timestamp for the last update of the status.
