[Kea-users] COMMAND_SOCKET_WRITE_FAIL

[Shobhith Chikku]

Hi,
I am getting this
*COMMAND_SOCKET_WRITE_FAIL Error while writing to command socket 35 :
Broken pipe*
 in logs when I try to execute the command

*/usr/bin/echo '{"command":"lease4-get-all"}' | /usr/bin/socat -
UNIX:/opt/tcpwave/timsdhcp/kea4-ctrl-socket | /usr/bin/jq*Other commands
are working fine, but only the lease command is giving this error.
How do I fix this problem?
Thanks in advance.

Below mentioned is my config file
