HP Tru64 UNIX and TruCluster Server Version 5.1B-5 Patch Summary and Release Notes (March 2009)

An issue in which new ICS server daemons and handles are created one at a
time each time the low water mark for each is reached, thereby causing a nanny
daemon to be called more frequently than it needs to.
—
— An issue in which no mechanism exists for the user to adjust the high and low
water marks for ICS free handles, which can result in poor performance during
rapidly increasing loads.
• Fixes a problem in which cluster alias connections are not distributed among cluster
members according to the defined selection weight.
• Fixes a memory leak in the cluster alias subsystem.
• Fixes an issue with ICS (Internode Communication Services) on a NUMA-based
system in a cluster.
• Fixes a problem in the cluster kernel in which a cluster member panics while doing
remote I/O over the interconnect.
• Fixes a hang that occurs when multiple nodes are shutting down simultaneously;
fixes a Cluster File System panic that occurs when using raw Asynchronous I/O;
and provides additional code to assist in problem diagnosis.
• Corrects a problem in which a panic displaying the message “error CNX MGR:
cnx_comm_error: invalid node state” occurs on a LAN cluster running under load
when other members are rebooting.
• Addresses an error in which caa_register -u produces with no balance data.
• Addresses a resource inaccessibility issue that can occur if the hosting member
crashes during a remote caa_stop operation.
• Updates the attributes on a directory when files are removed by a cluster node
that is not the file system server.
• Fixes a problem associated with non-SCSI storage.
• Corrects a potential security vulnerability in the cluster interconnect security
configuration that may result in a denial of service (DoS) on systems running
TruCluster Server software.
• Causes UDP datagrams that do not come from the correct port to be discarded.
• Addresses a node hang that occurs during the testing of Memory Channel cable
pulls. A cluster member may hang when a Memory Channel cable is pulled, the
node is taken down, the cable is plugged back in, and the node is rebooted.
• Fixes a cluster deadlock that may occur during a failover and recovery when direct
I/O is in use.
• Fixes a race condition in the Device Request Dispatcher.
• Corrects a condition that can cause excessive FIDS_LOCK contention when a large
number of files are using system-based file locking.
• Fixes a problem with cfsd core dumping shortly after startup if it is enabled or
shortly after enabling it. The problem fixed by this patch is only seen after applying
a recent dsfmgr patch.
• Corrects diagnostic code that could cause a panic during a kernel boot.
