Sai-Lai, Mike S.

Many thanks. I went with the StrandScavenger::killOutScavenger() option in my
XLL run-down code, and it works fine.

This is a known problem. A long answer can be found in:

http://www.uk.research.att.com/omniORB/archives/1999-09/0075.html

A short one is to add the option "-ORBoutConScanPeriod 0" to ORB_init.
Or add this call before calling ORB_init():

    omniORB::idleConnectionScanPeriod(omniORB::idleOutgoing,0);

Please let the list know if this solves your problem.
