I get this error message when I leave my code processing overnight (after work hours) and ALWAYS come back to this. I am utilizing a parfor loop to process many files simultaneously, but I don't believe the error stems from the parfor. I am also running the code in several remote servers (all separate from each other) so I can get more done overnight.

I suspect the problem is one of two things, but I don't know enough about the servers or have access to take a closer look:

1. The storage server is being "refreshed," or restarted. I'm not sure why this would happen every night.
2. The server running is somehow resetting the connection somewhere in the evening or night hours.

Servers are Windows Server 2012 R2 and have a separate NAS in the rack for storing the files.

Any ideas?

I can relate to the issue pertaining to the ‘PathHasBeenRefreshedEvent’ and ‘foundation::storage::vfs::Exception’ errors in MATLAB R2018a, which you are facing while working with network location workflows.

I faced a similar issue and found that updating MATLAB to R2019b or a later version resolved the problem for me. I suggest trying the same on your end to try resolving this.

I'd recommend that you use try-catch to save more detailed error information first.

Exceptions=cell(YourIndex,1);
parfor P=1:YourIndex
    try
        %Your job
    catch ME
        Exceptions{P}=ME;
    end
end
save('Exceptions.m','Exceptions');
