Hi,
my zaphfc is flooding my syslog with two messages (even without asterisk
running). Is this "normal"?:
--------------------------------------------------
zaphfc: bchan rx fifo not enough bytes to receive! (z1=1360, z2=1353,
wanted 8 got 7), probably a buffer overrun.
zaphfc: dropped audio (z1=2712, z2=2695, wanted 8 got 17, dropped 9).
With Asterisk running (asterisk -vvvvvgc) but without ANY activity it
prints these messages. Can anybody explain to me what the problem is?
Or is there no "problem"?:

Here's my suggestions anyway: 1. Are you using IDE disks on your server? You shouldn't, or at least you should set hdparm -u1 /dev/hd?. 2. cat /proc/interrupts to see if the zaphfc card is sharing irq with any other card. It shouldn't. If your motherboard supports IO-APIC you could try enabling it, otherwise try a different PCI slot. 3. Try removing other hardware that might require too much time during an interrupt. For example I had a r8169 network card that caused a buffer overflow every 10 seconds if the Ethernet cable was disconnected. 4. Use a current bristuff version (currently 0.2.0-RC8n). If you have several zaphfc cards in the same machine, try out Florz's patches <http://zaphfc.florz.dyndns.org/>. (Always get only one hfc card working before adding more.) 5. Your hardware might have problems with the many interrupts the zaphfc card generates. Some motherboards simply cannot take care of the 8000 interrupts per second these cards generate. Good luck! -- Best Regards, Tobias J?nsson, Lund SE

Can anybody explain to me what the problem is? > Or is there no "problem"?:Arik, I had the same problem until a few minutes ago. I found out that the device driver for my IDE controller was not compiled in the kernel, nor was it available as loadable module. So my IDE device was working without DMA and in 16 bit mode. That was the cause for my problems. Maybe it is the same cause for your issue. I have recompiled the kernel with via82C (my chipset) support and now the problems are gone. The driver was found under: device drivers -> ATA -> via82cxxx chipset support. When I now run hdparm /dev/hda1 it show me that the device is operating in 32bit DMA mode. I just thought to let you know in case you still suffer from this issue. Regards, Michel -------------- next part -------------- An HTML attachment was scrubbed...
