COMMENTS:
The debugger uses several sockets and in some conditions where the front
end does not initialize properly or abends, the debugged ECBs get hung
on I/O and the sockets never get cleaned up. This can cause a shortage
in the system of both heap storage and sockets. Also, some sockets the
debugger uses are never closed and the socket sweeper is needed to clean
them up.
SOLUTION:
This enhancement allows ECBs being debugged to exit and close all sockets
used upon issuing ZDBUG with the CLEAR parameter for a trace entry that
is currently displayed as "Act" in the debugger registration table. Both
C and Assembler debuggers correctly close all sockets. After applying this
APAR, some debugger sessions may continue to get hung when the debugger
GUI abends if off-load TCP/IP support with a CISCO router is being used.
In such case, it is recommended that the Channel Interface Processor (CIP)
microcode version be upgraded to the appropriate level.
