Failing Run Control

If the Runn Control fails, call Jon Paley right away. When he requests, go through the following steps:

  • Open a terminal on the NOVA-DAQ-1, and start the Run Control.
[novadaq@novadaq-ctrl-master ~]$
  • Look for the process rcWindow and copy its process id.
[novadaq@novadaq-ctrl-master ~]$ ps
  PID TTY          TIME CMD
 3428 pts/1    00:03:25 ssh
 3634 pts/1    00:00:04 python
 3635 pts/1    00:00:00 ssh
 3636 pts/1    00:00:00 python
 3645 pts/1    00:00:00 ssh
 3646 pts/1    00:00:00 ssh
 7910 pts/1    00:01:38 msgviewer
 7912 pts/1    00:00:00 rsrcWindow
 7914 pts/1    00:04:22 rcWindow
13238 pts/1    00:00:00 ps
23739 pts/1    00:00:00 bash
  • Open a new terminal window. Attach the debugger to the rcWindow process by refering its process id.
[novadaq@novadaq-ctrl-master ~]$ gdb -p 7914      

Jon Paley will probably tell you what to do next over the phone.
