If you end up opening a case with Oracle and getting it solved, I would be interested in hearing about it. We have a Mutex problem with 10.2.0.2, which is a pain because when it bites, one cannot log in via sqlplus, not even as SYS (or internal).

Can't reproduce at will, seems to occur irregularly - though I had 7 the past few days:

The times it happened basically reflect the times of activity on the system. As i stated earlier, it's a test system, and it's not being used daily. And even in repeating the very same application procedures; sometimes it dumps, sometimes it don't. Beats me.

Though I would do some very extensive testing before going into production with 10.2.0.2, especially if you run Intermedia as well (like I do on this system).

	Feh - when is this occuring?  I'm getting ready to go to
production with
	a bunch of RAC environments on RHAS4 64bit Opterons...
(worried look).                  

        Thanks
