I think the daqd process isn't running on the frame builder.
I tried telnetting' to fb's port 8087 (telnet fb 8087) and typing "shutdown", but so far that is hanging and hasn't returned a prompt to me in the last few minutes. Also, if I do a "ps -ef | grep daqd" in another terminal, it hangs.
I wasn't sure if this was an ntp problem (although that has been indicated in the past by 1 red block, not 2 red blocks and a white one), so I did "sudo /etc/init.d/ntp-client restart", but that didn't make any change. I also did an mxstream restart just in case, but that didn't help either.
I can ssh to the frame builder, but I can't do another telnet (the first one is still hung). I get an error "telnet: Unable to connect to remote host: Invalid argument"
Thoughts and suggestions are welcome!
