I'm not sure if this is an actual issue, but I'm curious to know if there is a known limit to the number of inputs a GUI transaction can handle?

When I tried to submit a consolidation transaction in the GUI for my full wallet balance (gathered across hundreds of blocks/transactions), the GUI was unable to produce the transaction. Despite trying multiple times, I always got the error message "Can't create transaction: failed to get outputs to mix: failed to get random outs."

I tried this with the CLI and it was able to produce the consolidation transaction (split into a couple of parts), so I believe the GUI behaves differently under this extreme circumstance.

Sorry, I may have gotten ahead of myself. This was observed on version 0.17.2.3. I did not try this with 0.17.3.0

spackle[m]: the GUI doesn't support splitting into multiple transactions

selsta: Oh, alright. I'm guessing there's a transaction size limit of 100kB, but I really just need to spend some time reading the code. Thanks.

yep, if you are above the size limit CLI will split it, GUI doesn't

at least I think so, I never tried it
