I have a gui-less flowgraph that runs in the background with sudo privileges. While I can run ControlPort normally from GRC, it doesn't seem to work properly with my backgrounded FG - I get timeout errors. My config files are setup so that both FGs do actually call ControlPort and Perf Mon (verified in log files). The FG and the monitoring apps are all running on the same PC.
Setup is Ubuntu 12.04 x64 with GR 3.7.4, built on the weekend.
Attempting to run Perf Mon, I get:
$ gr-perf-monitorx 127.0.0.1 23456
2014-05-22 11:01:54.450720 /usr/bin/gr-perf-monitorx: error: Traceback (most recent call last):

{
}
Attempting to run Ctrl Port Mon, I get:
and console output like:
$ gr-ctrlport-monitor 127.0.0.1 23456

{

...
My ctrlport.conf file has just one uncommented line:
ControlPort.Endpoints = tcp -t 5000 -h 127.0.0.1 -p 23456
I had extended the timeout, attempting to resolve the problem, but had no luck.
Very Respectfully,
Dan CaJacob
