If a fatal problem occurs during the initialization of Sun Cluster Support for Oracle Parallel Server/Real Application Clusters, the node panics with an error message similar to the following error message:
panic[cpu0]/thread=40037e60: Failfast: Aborting because "ucmmd" died 30 seconds ago
To determine the cause of the problem, examine the system messages file. The most common causes of this problem are as follows:
The license for VERITAS Volume Manager (VxVM) is missing or has expired.
The ORCLudlm package that contains the Oracle UDLM is not installed.
The amount of shared memory is insufficient to enable the Oracle UDLM to start.
The version of the Oracle UDLM is incompatible with the version of Sun Cluster Support for Oracle Parallel Server/Real Application Clusters.
A reconfiguration step has timed out.
To correct the problem, perform the appropriate recovery action for the cause of the problem and reboot the node that panicked.
