  fs.file-max = 500000

  • run command:

  sysctl -p

  • open file /etc/security/limits.conf, add follow config

  soft nofile 65535
  hard nofile 65535

  • open file /etc/systemd/user.conf, add follow config

  DefaultLimitNOFILE=65535

  • open file /etc/systemd/system.conf, add follow config

  DefaultLimitNOFILE=65535

  • reboot system, problem resolved

  reboot

For MACOS

  ulimit -n 20480

  • if you are running under bash, open file ~/.bash_profile, add follow config

  ulimit -n 20480

For docker-compose

  • if you started up okexchaind with docker-compose, edit your compose.yml and add

    ulimits:
        nproc: 65535
        nofile:
            soft: 65535
            hard: 65535

  • restarting docker-compose to apply new setting

    docker-compose -f ${compose.yml} down
    docker-compose -f ${compose.yml} up -d

2. Configure trust-node and chain-id

When using okexchaincli to query block/tx or send tx, the following errors may occur:

$ okexchaincli query block 6547302
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x4cecdea]

$ okexchaincli tx send boos okchain1hzttsww347hz7v3unp5g4834mxcte3pw8639ny 1tokt -y --fees 0.002tokt
ERROR: chain ID required but not specified

You should use the flag

$ okexchaincli query block 6547302 --trust-node
$ okexchaincli tx send boos okchain1hzttsww347hz7v3unp5g4834mxcte3pw8639ny 1tokt -y --fees 0.002tokt --chain-id okexchain-testnet1

or local configuration

$ okexchaincli config chain-id okexchain-testnet1
$ okexchaincli config trust-node true
