EVALUATION The dead lock shown in the stack trace looks very much like the one in 4904887. ###@###.### 2003-09-24 A CTE engineer has confirmed that the fix to the bug 4904887 also fixed this problem on the customer site. This means that the problem will not happen with the latest Tiger build. ###@###.### 2003-10-01
