Just experienced this issue. When closing files on server via FM Admin tool, the files says "closing" and nothing happens. I have waited up to 15 minutes and no change. The only remedy I found was to re-open Database, log in and log out which closed the files on server Admin. Experienced similar issue when opening files on server. Status will get stuck in "opening" mode. Remedy then would be to stop Filemaker Server Services on the server, re-start Server.
Restarting server helps but this is not a good long-term solution. Did anyone else experience this issue with FileMaker Server 11 or Advance 11?
