I also experienced this problem and the first thing that really helped out was changing the timing in the span line of the zaptel.conf. Change it to look like this (see below) and see if it helps out. I got the error much less after doing this and eventually got rid of the error completely by removing my raid drives, installing an IDE drive, enabling DMA mode on the Hard Drive, enabling APCI in
