Note that if you have a call to TSSetFromOptions() in your code (again, see
TS ex19 in src/ts/tutorials/ex19.c) then you can supply command line
options and see a lot of information about the timestepper. If you run the
example with the -help argument you'll get a big list of options which may
apply. Here's an example with ex19 which sets a small initial timestep and
then lets TSBDF adapt:
$ ./ex19 -ts_view -ts_monitor -ts_type bdf -ts_initial_timestep 0.0001
-ts_dt 1e-8
0 TS dt 1e-08 time 0.

As a bit of an aside, we actually just merged an option for TSSUNDIALS into
the main branch which might possibly give extra data here. If you supply
the -ts_sundials_use_dense option, it will perform a dense linear solve
instead of an iterative one. This is of course inefficient in most cases
and only works in serial, but it can be very helpful to eliminate the
possibility that the issue arises from the parameters of the iterative
linear solve.
