Description
We have contact records with custom fields, several of which are file fields. When merging duplicate contact records we are frequently - although not always - getting a fatal error.
The on-screen message: "sorry this service is not available".
The relevant log entry:

User reports that after a fatal error if they repeat the merge attempt it succeeds without further issues. As the issue appears not to manifest itself on every merge my assumption at this stage is that the fatal error is triggered only when certain custom file fields are populated (for example, field A might be populated in the original record and not in the duplicate, or vice versa). As I learn more on the specific circumstances that trigger the error I'll add to this issue.
