Check which version and build of Zoom you are running.

If it's not the latest, then you should update by reinstalling the Server Control from here:
http://www.wrensoft.com/zoom/aspdotnet.html

And re-indexing with the latest build of the indexer:
http://www.wrensoft.com/zoom/whatsnew.html

Let us know if you still have trouble with the latest build.

Ray,

We moved our website to the new Windows 2008 R2 server on April 10 and I was getting a lot of these warnings about Zoom. Then I realized that Zoom ASP.NET control was outdated because it was installed more than a year ago on that server. So, I re-installed Zoom ASP.NET control on the server at the end of April and re-ran the indexer. And still I get these warnings occasionally.

I have Zoom Indexer version 6 build 1028. ASP.NET Zoom control on the server says it is 1.0.0.

How regularly are the index files being updated? And how is this done? Are you indexing on the server itself, or are the files being uploaded via FTP?

It is possible that the error is occurring during the overwriting/updating process, when the files are temporarily out of sync or unavailable. This is particularly likely if you are uploading the index files via FTP without using the "Upload with .tmp filenames and rename when completed" option (as the index files can be large and may take some time to upload). Enabling this option should minimize the downtime.

Let us know if you still have trouble.
