Deadlock situation

Assuming this is code that was working before migrating to OSR6, There are some known record locking issues with OSR6, (not filepro record locking, any kind of file) but as far as I can tell they are supposedly only related to the Xenix binary emulator. Presumably none of your filepro binaries are so old as to be xenix binaries, but, just on general principle, have you installed MP3 ?
It's really unfortunate how SCO named and marketed OSR6 as being merely the next version of Open Server. Really, it's a completely different system from Open Server merely with a bunch of the Open Server userspace hacked in to make it sort of look like Open Server on the surface, from a distance, to a blind man.
Do not "upgrade" from osr 5.x.x to osr6.x.x without being prepared to handle, or at least live with, mysterious problems.
Mostly the osr5 emulation is ok, and installing maint pack 3 improves lots of things even more, but, it is still emulation and definitely still imperfect.
OSR6 is a really cool idea, but If you are not prepared to intuit and diagnose odd quirky behaviour of an open server user space tacked onto a unixware kernel, then do not use osr6. Use osr5. Disbeleive with extreme prejudice the marketing that osr6 is a drop-in upgrade from osr5.
Personally I would only install osr507 or make the larger change to linux or freebsd. Of those options, my actual choice is linux, which a lot of ignorant people will also say without any concept of why it's actually quite practical to use osr5 even today. But I say it and I am very much an anti-linux-zealot (read that either way) and even if you have lots of sco-specific code and scripts, it's still smarter imo to migrate and suffer the inevitable problems while learning the new system. I'd do that on my own not learn on some customer's back, so for today, I'd install osr507 while getting your stuff migrated to linux and tested on a box of your own. For this box that's already installed with osr6, try mp3, try the good filepro processing changes suggested already, and merely not install any _more_ osr6 boxes, even after you fix this one (since I'm sure it will work eventually, osr6 is not a completely broken system).
Good luck
