If the TotalView client fails to find a tvconnect request, make sure that the tvconnect process is writing its request file to the same directory being read by the TotalView client.
For example, the client may read the wrong directory if your home directory on the node where tvconnect is running is different than the node where the TotalView client is running.
When setting this variable, make sure that it points to a directory accessible by both the tvconnect and TotalView client processes, and that it meets all the ownership and permission requirements.
