Progress 8.3E
SYMPTOM(s):
muxfree not owner ( 3719 ) error and database shutdown
muxfree %i<latch-id> not owner. (3719)
Database shuts down abnormally
CAUSE:
Customers have very occasionally seen errors in the past in our MUX latching code, e.g.
muxfree %i<latch-id> not owner. (3719)
This error results in an abnormal shutdown of the database.
The MUX latches are turned on only when the -spin parameter has been
set. When -spin is set, we call the routines mtlkmux() and mtfrmux();
otherwise, we call routines mtlatch() and mtunlatch().
The Version 8 and 9 MUX latches can be turned off by specifying -mux 0 on the broker startup command. This is an undocumented startup parameter. It only has an effect if -spin has been set, and should only be used if MUX latch errors have been seen.
FIX:
Specify -mux 0 on the broker startup command
