The case is reproduced if the pgpool configuration has the values like: delegate_IP = '192.168.110.34' if_cmd_path = '/etc/pgpool-II' if_up_cmd = 'vip_up.sh' if_down_cmd = 'vip_down.sh' The 'if_up_cmd' and 'if_down_cmd' commands have no placeholders for the VIP. |

Hi Pgpool Developers, Can you please clarify the information on the status of this issue? Thank you! |

Hi I am not able to reproduce this issue. Can you produce it reliably or does it happen randomly? Can you also share the Pgpool.conf file and the core dump if possible. Thanks |

Hi, the issue is easily reproduced with command: # pgpool -n -f pgpool.conf several core dumps together with full configuration files are attached.
