[Asterisk-Users] Fax server (TxFax) fails during transmission

I'm having an intermittent problem with fax transmissions, something I
call the streaking mascara syndrome.
TxFax will be part way through a transmission when something fails--on
the fax printer, part of the page will have correctly printed, but the
rest of the page is "streaked" to the bottom.
I have several successful multi-page transmissions interspersed with
streaked transmissions, so I believe it is a timing problem, not a
software problem. The fax machines are an HP5500 and an industrial
strength Konica(?).
During one successful transmission, I tar'd a large directory without
incident. This leads me to believe it's not processor or disk usage
causing the problem.
I'm not running X, and I've switched off all unnecessary services. I do
have asterisk and qmail running on the same box. Asterisk is only doing
the TxFax function and does not have any voice calls as yet. I've
renice'd qmail to +10 without effect.
Does anyone have a method to trace this problem? Is there some way to
monitor the PCI bus and interrupts? Any suggestions would be appreciated.
Thanks,
