Description
I noticed this while we were having some network problems at the SNS.
I had last run the algorithm LoadSNSEventNexus using the file /SNS/SEQ/2010_2_17_SCI/1/6745/NeXus/SEQ_6745_event.nxs. The directory /SNS/SEQ is a automount point for the data archive.
If I try to run this algorithm again when /SNS/SEQ is not available, MantidPlot just hangs with a blank screen.
Running through strace I get as the last line ...
stat("/SNS/SEQ/2010_2_17_SCI/1/6745/NeXus/SEQ_6745_event.nxs",

It is if the network is lost at the point of running the algorithm the next time.

Bulk move of tickets to iteration 27, if your ticket is essential for Iteration 26 then move it back.

Oops, forgot to assign it back to you.
If you actually delete the file in between accesses, then it is fine. This is probably only a problem for network drives that are unstable.

There are limits to what we should be able to handle. The file disappearing while we are loading it is going to be rare.

The problem seems to have gone away anyway.
I tried loading a file, removing the mount point then running the algorithm and it simply said that the file doesn't exist.

This ticket has been transferred to github issue 2787
Stuart,
Could you add a bit more detail. Is this is we loose network connection while loading a file? Or is it if we lose connection after the workspace is loaded, perhaps while doing something else?
Assign it back to me once you answered.
