[Discuss-gnuradio] Flow graph stops after 45/60 minutes (was: Re: Discuss-gnuradio Digest, Vol 142, Issue 15)

[Marcus Müller]

Hi Dominique,
please, please, please, don't respond to digests, leaving the subject line unchanged; it's completely impossible to match mails to conversations without searching one's inbox. (it's also in the first line of the digest...).

So, if you're running your flow graph for 60 minutes and it produces 250kS/s, that totals to 3.6*250MS = 0.9GS.
Now, assuming you save complex float (which is 2x float32), that is a whopping 8B/S*0.9GS = 7.2GB.

By any chance: How full is your hard drive? Or do you write that data to RAM? Are you using a file system with a maximum file size (FAT32)?

Again, what you're offering for debugging purposes is not really much. However, I can assure you that the file_sink usually works perfectly over long times. Martin has already given you some hints of what could be interesting, maybe you could fill us in on these?

Greetings,
Marcus

 Hi,
Now my GRC runs for 45-60 minutes only, after that the flowgraph is
 killed on its own.
No error message provided.
 Anyone can assist?

You're probably running the 'lite' version of GRC, which has this
limitation....

Just kidding! There's no lite version.

However, no-one will be able to help you without some more info; which
version, what's your FG, what's the smallest FG you can create which has
this issue, have you tried tracking it down to a specific block...

Cheers,
M

I Martin,
The GRC runs properly with no problem. But I discovered that the problem starts when I use the File Sink block to store my data. 

When File Sink block is activated, my GRC runs for about 60 minutes and shuts down automatically.
I have a very simple flowgraph: Usrp source with 2 channels, 1 Multiply block, 1 Scope Sink, and 1 File Sink. My system sample rate is 250 Ksps.
I tried to change the sample rate, but no luck still.

Any help please.

Dominique.

Hello Tom,
Is there a timeline for fixing the issue with control port and backing it
to its normal operation?

Best,

That doesn't specify what the underlying concern was.

Nope. No it doesn't.

Pleas help me to use control port monitor.

You can't.

See a mail from Tom Rondeau a few weeks back : ctrl port has been
temporarly removed from gnuradio due to some issues with its
middleware. It's being worked on.


Cheers,

    Sylvain
