That was it. The application was creating temporary LOBs with
duration set to SESSION, and not explicitly releasing them. Since
this particular app uses persistent DB connections, it just kept
creating more and more of the beasties until eventually the tempspace
was exhausted.

The developers have updated their code, and are testing the changes
now. If all goes well, the fix will be implemented sometime this
weekend.

Thanx to everyone for your assistance... especially Steve Rospo, who
got me facing in what turned out to be the correct direction. :-)
