Debug

• Error: ENFILE: file table overflow

  • Reason: MAC default setting too low.
  • Solution：sudo sysctl -w kern.maxfiles=65536, sudo sysctl -w kern.maxfilesperproc=65536

• Error: replacement transaction underpriced

  • Reason: Send too fast, so nonce repeat.
  • Solution1: Now temporarily use the queue to process transactions
  • Solution2: Try to change to batch transactions in the future

• Error: out of gas

  • Reason: quorum(ref)
  • Solution: Specify a high gaslimitsend({from: ADDRESS , gas: GASLIMIT})
