Sound Recoder Error: could not allocate DMA buffer

["Laurent POIROT" <Laurent@medianet-usa.com>]

After several recordings of wav files with wavrec, i have this Sound Recoder
Error: could not allocate DMA buffer that comes out. I have no idea when
this come from. I use a crontab to make a recording from that soundcard for
5 minutes on a wav file and i do that every 30 minutes. It works perfectly
for a while until this error, if you have any idea, please let me know. I
use Linux Redhat 5.2 with a SoundBlaster Pro ISA. Do you think that changing
the sound card would change this problem ?

thanks
