we are encountering an issue where an Index file keeps growing indefinite until the special partition for it becomes full and causes it to be come corrupted, which the indexer then deletes and rebuilds.
From my understanding the indexing file should not really go over 100gb, but this cycle continues month after month and increases to around ~350GB.
This is a remote desktop server where all of an office works and relies on the searching service to search for emails in outlook so disabling is not an option.
Emails are done through IMAP and hosted on the same server. Only certain folders are being indexed (data folders etc)
