Abstract
A method and system for capturing a state of a distributed computer system is provided. The state is captured in response to an error or event message received by one of the clients and/or server nodes of the system. In response to receipt of the error or event message, the recipient initiates transmission of a special protocol message of affected members of the system. Upon receipt of the message, all recipients will conduct a freeze of their respective operating system image. Depending upon the characteristics of the error or event, the message may be transmitted to a selection of members of the system, or the entire system.
