****************************************************************
A Daemon may receive an ENF signal asking for information about
a particular server instance.  If both the target and origin
systems have ever had more than 10 active controllers, then an
error occurs attempting to iterate the active server list and
an infinite loop can result.
Problem conclusion
The incorrect traversal of the ASRT (bbodasrt.mac) chain is
updated to correctly find the next ASRT.

APAR PQ86406 is associated with SERVICE LEVEL W502006 of
