Title: Out of memory errors
Hello Henry,
The call to mlockall()
fails to lock the RAM area used by Linrad.
Maybe your RAM is reserved for a large RAM disk or
there is
some other program running. Are you perhaps running in
a console
under X?
The calls to mlockall() were added recently because I
have had
reports indicating that some Linrad users run Linrad
off the hard disk
(swapped by Linux) The behaviour is a bit
unpredictable...........
Linrad does not need much computing resources. I
uploaded a screen
dump today after verifying Linrad-00.15 on a Pentium
133 MHz. The
image shows seven hours of (simulated) VLF waterfall at
a FFT bin
width of about 0.005 Hz. The soundcard was sampling at
22050 kHz
which is much higher than typically needed. Yet the CPU
load was below
50% and about 5 megabytes of ram was
used.
So, Henry, I am pretty sure your computer hass the
memory needed,
but I do not know why Linrad is denied to lock it.
Unless someone else
gives the explanation, please give more
details.

Hi,
I'm getting
"out of memory" errors with Linrad 1-.15 regardless of the parameter settings.
Any suggestions?
