RE: [linrad] Out of memory errors

Title: Message
Hello Leif,
Thanks for your answer and sorry about the curt email.
I was using an x-console which does use a lot of memory. I then tried running Linrad from runlevel 3. Still did not work and received the same error message. Linux reported 217 Mbytes free and I have a 128 Mbyte swap space. So there should be plenty of memory.
Any further suggestions would be appreciated.

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.

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