Eos Ram bug!

Hi, I have buy/sell RAM from RAM market without problem for a week but today I have facing with RAM bug.

FAILURE
TRANSACTION HAS FAILED

{"CODE":500,"MESSAGE":"INTERNAL SERVICE ERROR","ERROR":{"CODE":3080004,"NAME":"TX_CPU_USAGE_EXCEEDED","WHAT":"TRANSACTION EXCEEDED THE CURRENT CPU USAGE LIMIT IMPOSED ON THE TRANSACTION","DETAILS":[{"MESSAGE":"BILLED CPU TIME (2843 US) IS GREATER THAN THE MAXIMUM BILLABLE CPU TIME FOR THE TRANSACTION (0 US)","FILE":"TRANSACTION_CONTEXT.CPP","LINE_NUMBER":361,"METHOD":"VALIDATE_CPU_USAGE_TO_BILL"}]}}

I have also try to manual create transaction by eosjs, EOSToolkit, FeeXplorer. All those tools show I have 2MB and I can't sell even if 8192 bytes.
Someoane can help me?
