What does the "stale oracles" error mean?

marginfi has chosen to use decentralized, trustless oracles. These oracles are managed by providers, like Pyth. During periods of blockchain congestion, oracle providers may struggle sending pricing data. If pricing data is stale during a user interaction, marginfi does not enable users to perform oracle-dependent actions. This is to prevent manipulation based on incorrect oracle prices. marginfi is working directly with Pyth, Switchboard, and Solana Labs on correcting these issues on behalf of the user.
