[omniORB] 4.0.7: reference to servant becomming nil after some time

[Igor Lautar]

Hi,

Is it possible that an existing reference (_narrowed to valid ITF)
becomes nil?

Either by changing network configuration (IPs etc.) or something else.
Is it at all possible that this occurs, excluding omniORB bugs (is such
a bug in 4.0.7?)?

Our code is roughly the following (pseudo):
 1) string_to_object
 2) _narrow to itf
 3) check nil
 4) use

It once (only once) happened that after some time (observed after 2
weeks of client uptime) of running, reference became nil. It couldn't be
nil at the start as there is a check for it.

It could also be some memory corruption (writing where we shouldn't).

Ideas/comments?

Regards,
Igor
