I don't know of a lib problem here, but there could be. I would
recommend trying to create a small/simple test case that reproduces the
problem (if you can't make the simple case reproduce it's probably some
larger problem with your code, if you can make it reproduce then your
test case will allow me to debug dbus)

This limitation isn't the max message size, just the max signature size.
Probably your message should have a single array argument instead of a
whole bunch of separate arguments.

i.e. instead of the signature "int, int, int, int, int" you want
"array<int>"

If you have multiple types then do array<variant>
