So, what else is writing to the FIFO? lsof or fuser should be able to tell you.

What kernel version are you running?

No other processes are accessing the FIFO. There is a FIFO.faxCAPI, which is accessed (only) by c2faxrecv, from capi4hylafax-01.02.02.
Kernel is stock 2.4.28, with a few patches (linux-default-bsd-mppe, i2c-2.8.8, lm_sensors-2.8.8, bcm5700-7.3.5, pptp-conntrack-nat and ea+acl+nfsacl+sec-2.4.25-0.8.71)

Any chance you can try it on a stock kernel, without all the extra patches.

The reason I'm driving this way is because faxq is clearly doing things
correctly, as it's been programmed to.

Your strace shows that:

1) faxq uses select to request of the kernel if data is available for
reading.
2) The kernel returns that yes, there is data available.
3) We read it and act on any messages.
4) Repeat

There is something with this setup which is causing the kernel to
continuously tell us there is something to read, but nothing is read.

Is your spool over NFS? Any funky EA, or ACL on the FIFO?

Stock kernel 2.4.28 without patches shows identical behaviour. The spool is on ext3, no special things. Would etc/config* or the kernelconfig be of any use?

It turns out faxq only starts looping after running "faxmodem faxCAPI" or after starting c2faxrecv.
I suspect an old version of capi4hylafax (currently version 01.02.02). I'll try to find a newer version
and see if that changes anything and i'll post the results here.
