File-server Problem Wednesday Afternoon
We had a problem with the connection between the main file/web/mail server (ms.mcmaster.ca) and the primary storage array this afternoon. File access - and thus all other kinds of access - became spotty at 3:46 pm, then became read-only and then was lost altogether. Things are OK again as of 4:15 pm.
There is no reason to believe that any files or mail messages were lost.

Mail Delay Thursday Afternoon
Mail delivery was spotty for a couple of hours on Thursday afternoon. The logjam was broken at ca. 3:30 and several hours worth of mail came through in a rush. There is no reason to believe that any deliveries failed.

Big Jobs, Long Jobs, Scratch & Screen (revisited)
(This is an update of an earlier blog entry about the same thing).
There are two little things you can do to make large or long-running jobs easier for you and less stressful on the file server: use screen and scratch, respectively.

OS X Lion and the Math & Stats Mail Server

The problem is particular to the latest version of Mail and UW IMAP (one of the standard unix mail servers).
In the Apple discussions forums, there are three solutions which appear to work - though none of the solutions seem to be universal (for varying reasons). For OS X Lion users who connect to the Math & Stats mail server, I recommend trying solution 1 below first, and then solution 2 if the former does not work. Solution 3 is documented here for completeness; I will resort to recompiling the mail server as a last resort.
Important note re. password length: it appears that another requirement is that your ms.mcmaster.ca password be no longer than twelve characters. I have yet to verify this with another server or to have corroboration from another source, but it is most certainly the case that Lion Mail will not authenticate with mathmail unless my password has twelve characters or fewer. Before proceeding any further, change your password if it is longer than twelve characters.
1) Turn SSL off and back on
- go to Mail -> Preferences -> Accounts
- select mathmail account
- go to Advanced tab
- uncheck "Use SSL"
- close Preferences
- re-open Preferences and check the "Use SSL" box
I note that this did not work for me, though others have reported success.
2) Remove Mail Settings and Start Fresh
The following will cause of your mail settings and local mail folders to disappear (though they will be recoverable). I recommend that you contact me if you have other accounts defined of if you are at all unsure.
- quit from Mail
- open Terminal
- cd ~/Library
- mv Mail Mail.2011mmdd
- open Mail
- go through setup again; details here
This worked for me.
3) Patch UW IMAP server
An Apple Support Communities user makes a convincing case for patching the UW IMAP server code. Apparently, Apple Mail is now making a legal but heretofore rare authenticate request which omits the first first field.
