Method Timeout Behavior is Changed

A description of the change in the behavior of method timeouts in the Sun Cluster 3.2 release is missing. If an RGM method callback times out, the process is now killed by using the SIGABRT signal instead of the SIGTERM signal. This causes all members of the process group to generate a core file.

Avoid writing a data-service method that creates a new process group. If your data service method does need to create a new process group, also write a signal handler for the SIGTERM and SIGABRT signals. Write the signal handlers to forward the SIGTERM or SIGABRT signal to the child process group before the signal handler terminates the parent process. This increases the likelihood that all processes that are spawned by the method are properly terminated.
