Solend V2 introduces collateralization limits, which are global limits on how much can be borrowed against an asset. For example, a collateralization limit of $20M for SOL means only $20M of borrows can be secured by SOL collateral.
If the collateralization limit for an asset is hit, increasing borrows against that asset (via borrows or withdraws) is not allowed. Additionally, any obligation that violates this limit can be marked as closeable by the lending market owner or risk authority. A closeable obligation can be liquidated without penalty.
