Random hangs at startup or when accessing mail in Notes on Mac OS X 10.7

Technote (troubleshooting)


Problem

If running on Mac OS X 10.7, Notes clients may hang at startup or upon launching or accessing the mail inbox.

Cause

The default semaphore mechanism for Notes conflicts with changes introduced in Mac OS X 10.7. See below for a possible workaround and information on future plans for support of Notes on Mac OS X 10.7.

Resolving the problem

The Notes 8.5.3 release resolves the issue described above of random hangs at startup or when accessing mail. In Notes versions prior to 8.5.3, and in pre-release versions of 8.5.3, the same fix can be enabled via notes.ini (steps provided below).

NOTE: This workaround is provided for informational purposes only and does not imply formal support for pre-8.5.3 versions of Notes on Mac OS X 10.7. Also, IBM does not have plans to formally test Mac OS X 10.7 with versions of Notes prior to 8.5.3, or to formally support this workaround for versions prior to Mac OS X 10.7.

Steps to configure Notes to use POSIX semaphores.
1. Shut down Notes.

2. Navigate to your Notes Preferences. Note that the Library folder is now hidden in 10.7. You can get to it by launching 'Finder,' clicking the 'Go' menu and then holding down the 'Option' key to select.



3. Navigate to your 'Preferences' directory

4. Edit 'Notes Preferences' and add the following line:
POSIX_SEMAPHORES=1

5. Restart Notes.
