Hi all,
I created a container with lxc-2.07 on android 9.0 mobile phone which based on ARM_64 platform, the kerne version is 4.4 for android mobile phone, and the lxc-checkconfig fully meets the requirements. when I start the container, it will reboot repeatedly. the following is the the important log:
lxc_start - start.c:post_start:1439 - Started “/init” with pid “4519”.
lxc_start - start.c:signal_handler:322 - Invalid pid for SIGCHLD. Received pid 4506, expected pid 4519.
lxc_commands - commands.c:lxc_cmd_handler:893 - Peer has disconnected.
lxc_commands - commands.c:lxc_cmd_handler:893 - Peer has disconnected.

lxc_commands - commands.c:lxc_cmd_handler:893 - Peer has disconnected.
lxc_commands - commands.c:lxc_cmd_get_state:578 - Container “con1” is in “RUNNING” state.
lxc_start - start.c:signal_handler:326 - Container init process 4519 exited.
lxc_start - start.c:__lxc_start:1375 - Container “con1” is rebooting.
At the same time, I find that the PID was constantly changing as below:
Name: con1
State: RUNNING
PID: 6308
IP: 192.168.9.2
CPU use: 0.37 seconds
Name: con1
State: RUNNING
PID: 6229
IP: 192.168.9.2
CPU use: 0.36 seconds
Name: con1
State: RUNNING
PID: 6150
IP: 192.168.9.2
CPU use: 0.34 seconds
Not sure how to debug this issue. any way to debug and resolve this?
Thanks a lot.
BRs,
Deven
