Dear SteveO and Armin,
Thank you for giving me information.
In fact, my netpi's time was incorrect. However, after correcting time settings, the problem still occurs.
I found the messages in syslog that indicate dhcp server started, when the problem occurs.
However, I am not sure the situation is the same as you.
In my syslog, the below sequence repeated more than 10 times,
and finally, child respawn is stopped for 300 seconds,
then, dhcp server started as below.(However, dhcp server does not works actually)
(It seems little bit strange. dhcp server started twice?)
During the problem occuring, repowering does not solve the problem. Since, when I found the problem occuring, get a syslog and repower, then reget a syslog, and make a diff file, which has information about only single running. Attached is this diff file.(My privacy info, such as host name, is replaced)
Since I can not judge which logs are related to the problem, please reserch this file.
Best regards,
