Hi gurus
I try to make a linux recorder which record continuesly DVB signal. My
problem is that after 2-4 days it frees because size of VMALLOC is too small
?
Here is my situation after DVB freeze out:
[root@refrecord DVB]# /DVBVIDEOT/DVB/dvbtune-0.5/dvbtune -f 658000000 -i

Ok. So it seems that VMALLOC is the problem. Is there a way to fix this ? I
need to get this so stable that it works without rebooting the server onace
a night. Any suggestion ?
Any help would be highly appreciate
