Notes on Dual Processor Mac Hangs Intermittently When Clicking Mail Icon on Welcome Page

Technote Number: 1169906


Problem:
This issue was reported to Quality Engineering as SPR #EHET5YHV8N and has been
fixed in release 6.0.5 and 6.5.4.

Excerpt from the Lotus Notes and Domino Release 6.0.5 / 6.5.4 MR fix list
(available at http://www.ibm.com/developerworks/lotus):
SPR# EHET5YHV8N - Fixed a serious problem on the dual processor Macintosh
platform in which the Notes client would hang unpredictably. The problem is due
to failure to implement atomic operations for the Macintosh platform. That
failure is now corrected. The default implementation used nonatomic
instructions, which are not a problem on a uniprocessor, but extremely risky on
a multiprocessor. A workaround would be to disable the Dynamic Client
configuration, in the preferences file. This problem has been fixed in 6.0.5
and 6.5.4.

To temporarily resolve the issue, force quit (using the Command - Option -
Escape sequence) the frozen Notes application and kill the NotesDynConfig
process.

In at least one case, disabling the Dynamic Client configuration in the
Preferences file for some machines was a viable workaround; however, this was
not successful on all machines. To enable (0) or disable (1) the Dynamic
Client Configuration, add the following parameter in the Notes Preferences file.

DisableDynConfigClient=1

For additional information on editing the Notes Preferences file, refer to the
technote titled "Notes Preference Editor for Notes 6.x and Mac OS X" (#4005829
).
