Bob:

This issue was occurring in DC v8.1. It is caused by something running. The problem is what is running. For us this only occurs at sites with large databases. My theory, as reported earlier in this issue, is unchanged. WinZip creates a temp file first and then writes it to the DC####.zip file. My theory is that sometimes this is interupted by DC itself starting the next step because it fails to see that the write out from the temp file is still in progress.
