If chat is unresponsive, it can be brought back without interrupting other Vista services.
The process is simply to kill the java Chat/Whiteboard process on each node. Vista will automatically restart the process once they have been killed.
Repeat these steps for each application node in the cluster.
- As root type _ps -ef | grep chatwb_ This should display the java process for the chat/whiteboard service. _Note the PID of the process._
- run _kill PID_ where PID is the PID of the chat process from step 1.
- periodically run _-ps -ef | grep chatwb_ until the process reappears, it should take less than a minute.
