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,
