Advanced Communications Controller B.03.30 Release Notes (January 2002)

ACC Release Notes
Patches and Fixes for this Version
Chapter 1 9
• JAGad09926
Symptoms: x25init fails with the following message:
[x25stop] X.25 interface zx25m0p2 has been stopped
ixetune: IXE_SNREG ioctl failed: Invalid argument
Too many IXE lines configured in /etc/netconf
Defect/Fix: The fix is in the application using X.25. If an application is using the X.25
subsystem with ACC, and if the "zmasterd stop" or "zmasterd kill" command is issued, a
"x25stop -K" command must be issued. The "x25stop -K" command should be issued after
doing the zmasterd stop/kill command. This is necessary because the zmasterd stop/kill
command deallocates the ZCOM data structures and there is no way the X.25 subsystem
would know that the data structures have been deleted. If the "x25stop" command is not
given, then all successive "x25init" commands may give error messages stating that the
"x25tune" command failed.
• JAGad13782
Symptoms: Multiple connections over ACC/X25 are made. After 5 days of intensive stress
on the machine it needs to be rebooted because of a memory leak in the 512 bucket. The
problem can be reproduced on all possible hw systems running HPUX 11.00.
Defect/Fix: A code segment does an exit before freeing a buffer. The fix is to assign the
buffer to the free buffer area before exiting.
• JAGad14557
Symptoms: The defect occurs when the system is under extreme load and there is large
amounts of queued data that has not yet been transferred to the card.
Defect/Fix: Under these conditions, if a call is cleared and then immediately reestablished,
the data for the prior call can be transmitted on the new call. In other words, the data for
the previously established VC can be sent on the newly established VC on the same ZLU.
The changes are to flush the physical driver's high and low priority transmit queues for
the VC whenever a inbound or outbound clear request is received.
