Unable to MapViewOfFile in MapChunk ERRORS

I have to say since starting to play poe i have not experienced any bugs at all though i know there must be some out there.

Today I have been getting this error nonstop when I try to switch certain maps and once when piety died, but mostly when I try to zone to certain maps (act 3 and act 1) hasn't happened in act2 yet.

This is the error:

Unable to MapViewOfFile in MapChunk.
Error Code:8
Offset:988938240
Size:16705089

This is happening to me at an incredible rate and it's making the game almost unbearable to play. Is there anything I can do to fix this or is it a bug that they are working on?

Thanks for any help.

ok thanks
