Temp Table Space Gobbled Up

How do I find the culprit here? Running Online 5.03 UC1 on HPUX 9.0. I have 120Mbytes reserved in rootdbs for temp tables and some user has gobbled up virtually all of it and apparently gone on vacation. How do I find the owner and blow him off? Some sample tbstat output follows.
