If this is a correct assumption, then I think this could be the result of the same caching bug that I talked about sometime back in 3.7.5, which is fixed in 3.7.6.The issue could cause the new client to not see the correct size and block count of the file, leading to errors in reads (perhaps triggered by the restart of the vm) and writes on the image.Cool, I look fwd to testing that in 3.7.6, which I believe is due out next week?thanks,
