Serviceguard for Linux Version A.11.16 Release Notes
Patches and Fixes in this Version
Chapter 148
Fixes
The following defects have been fixed in HP Serviceguard for Linux
A.11.16.02.
JAGaf49627, JAGaf50940, JAGaf46380, JAGaf56322: IP addresses
in the cmclnodelist file and /etc/hosts are treated incorrectly
• Problem: Serviceguard was not handling IP addresses in the
cmclnodelist file correctly. This resulted in “Permission Denied”
errors in response to commands. (This was only an issue before the
cluster was configured. Once a cluster is configured, the
cmclnodelist file is ignored and access is controlled via the access
control policies (ACPs) specified in the cluster configuration file.)
Additional issues prevented proper IP address resolution in
determining ACPs.
• Resolution: Code now compares the IP address of the sender to any
IP address listed in the cmclnodelist file. The code will also now
keep searching the ACPs until the hostname with the highest
privilege is found.
JAGaf57378: Memory leak in cmcld
• Problem: The cmcld process continues to consume memory and
increase in size over a long time. There were cases during cluster
reformation where the code was not freeing some memory that it was
no longer using.
• Resolution: The routine to free memory was not always called when
it should have been in the package manager code. The fix is to
change the code so that it frees the memory when it should.
JAGaf57613: cmcld hang and possible TOC
• Problem: The cmcld process hangs and there may be message in
syslog like “Warning: cmcld process was unable to run”. Additionally,
the cmcld process may be killed by the hang detector and the system
will TOC.
