15.19 Running supportconfig Concurrently on Multiple Nodes Causes Cluster Problems

Running the supportconfig command concurrently on multiple nodes can cause the multiple nodes to lose communications with the others and go down.

Micro Focus Support provides the supportconfig package to customers in order to gather configuration, log, and error information from both the installation of the OS and from varying applications. The supportconfig command was designed without clustering considerations. The command is normally run after a server experiences problems. It is not a good idea to run the command concurrently on multiple nodes in a healthy cluster. If you need to run the supportconfig command on multiple nodes in a cluster, run it on one node at a time.
