Local cycles minting limit

Developers

I’m attempting to test high canister volume locally today using DFX and I’m hitting some kind of limit after creating ~400 canisters.

❯ dfx ledger create-canister --amount 1 $(dfx identity get-principal) 
Transfer sent at block height 1935
Using transfer at block height 1935
Refunded at block height 1936 with message: More than 50_000_000_000_000_000 cycles have been minted in the last 3600 seconds, please try again later.

❯ dfx --version
dfx 0.18.0

What is this limit, and can I remove it?

The Cycles Minting Canister (CMC) imposes a rate-limit of 50P cycles minted per hour which is hard-coded in the canister and thus cannot be changed.

I suppose I can tweak the cycles / ICP rate, or reduce amount of ICP used when creating canisters. Thanks!
