Re: Flamp Segment Fault using Script

Mike P.
 

WT, I am surmising that the only thing that is
changing is the size of the file(s) that you have
been sending. If the current file sizes are larger
than before, perhaps the scheduled transmissions
are stepping on each other before the prior one
has finished.

Try spacing out your EVENT TIMES and see if
that helps. I'm not sure if that is the problem but
I would be interested to know how you fare.

I use Flamp to send a Sunday Night Bulletin to our County's ARES membership. The bulletin is
in HTML format. Last January I decided to dive into the Flamp Scripts so that I didn't have to sit
and watch the computer while it sent the bulletins. It has been working rather well until 2 months
ago. When the time happens to kick off the Flamp at 0200Z Flamp segment faults. The worst
part of it is that it is not happening consistently. 3 weeks ago it worked. The past 2 weeks
including tonight it faulted. I have been trying to figure it out for 2 months without much success.

Here is a sample of the segment faults:

Attached is the script and the bulletin for tonight. Any ideas would be helpful as to what I am
doing wrong.
