A question about pending in ORBIT server

[Jeff Cai <Jeff Cai Sun COM>]

Hi, all
In Evolution, when I new an appointment, sometimes the client and server
will hang.
I found it is because the server doesn't return timely.
And Now I don't know how to start to solve the problem.
I hope anybody can give me some suggestions such as is it a problem of
ORBIT or which can cause Orbit hang?

You can see the server's trace, and please focus on the code of ORBit.

In server's code, it sends another corba request which doen's return
timely. This makes the server hangs.
