We are using Fault Analyzer, which writes a TDUMP whenever it cannot do 
anything else. That TDUMP could later be used to analyze the fault. Fault 
Analyzer very conveniently also picks up after itself and deletes its own 
tdumps when it cleans up the fault history file.

And then we run the brave new world called 'the brokers', which is my 
generalized not quite correct name for a bunch of address spaces. They also 
write TDUMPs, or rather, JAVA does. Liberally sprinkled, as Sam puts it, until 
we noticed (because these things run as STCs and the STC userids here are not 
allowed to allocate datasets) via lots of RACF violations and forced JAVA to 
use the same HLQ that we had already in place for Fault Analyzer. And yes, IBM 
had a look at those, because there was nothing else available for a sev1 
production problem!
