I'm too swamped to build a test-case, but here are straces
that show the relevant system calls and the failure.

The 'daemon_strace.txt' file is of the master daemon
that creates all the segments and provides a service.

The 'client_strace[12].txt' files are of a client daemon
that attaches two segments, does some work, and then
quits.

The first client trace shows the first invocation, which
is successful.  The second client trace shows the second
invocation, which fails.  All other attempts to attach
the segment fail, and the daemon cannot be successfully
restarted until the system is rebooted.  I.e. the
kernel is getting hosed.

Happy to answer any questions and provide more details
if desired.

Regards
