That's why it's called "transient"!

Transient space represents disc space that's holding virtual memory. If
you have large number of processes that complete at in a short interval
(or a small number of processes that use a lot of memory), you'll see
this as they return their main memory resources.

One of our clients has a network application that adds server processes
as the load increases. By evening on a busy day, there might be 300 or
more of these hanging around, mostly doing nothing. If we reset the
server so that idle processes are killed, available transient space can
increase by 2 million sectors inside of 10 seconds.
