Memory leak in VERITAS Cluster Server's link monitoring process (halink)
VERITAS has recently discovered a memory leak issue with its Cluster Server product (VRTSvcs 1.x). This problem
only occurs if the LinkMonitoring attribute in the cluster configuration is enabled, and may take several days in order
for the system to encounter any significant performance degradation.
If enabled, VERITAS Cluster Server (VCS) will start up a halink process, which will send notification to hagui in case of a down private heartbeat link. By default, this attribute is disabled.
Who is at risk:
All VCS 1.x installations on Solaris and HP, and VCS 1.2 on Windows NT 4.0 with LinkMonitoring attribute enabled. Current setting of the attribute can be determined from 'haclus -display clustername' output or from VCS' main.cf file as shown below:
