I am having the same problem mentioned. Basically the indexer freezes during the archiving process. We then try to re-index with the same problems. No error messages show. We are using Archive To Go version 1.5 with indexer version 1.5.0.0. The Groupwise archive file is approximately 9 gb that I am trying to archive and index. The free space on that hard drive is approximately 60 gb. Please advise.
