I cannot confirm for each of the machines, but I know that on some of them where the issue happened, no virus scanner were installed apart from the default one of Microsoft, and I did not see any other processes than postgres using the file when I looked with Process Explorer, do you know how I can be 100% sure that it was not the case ?
Thanks in advance,
Thomas

Did you make sure that no virus scanner is active on the data directories?
