The error is reported as follows:
LOG save error!LogFd =NULL ,errno 24,reason = Too many open files
The above error is printed using the following:
printf("LOG save error!LogFd =NULL ,errno %d,reason = %s\n", errno, strerror(errno));
You can see a prompt saying that there are too many opened and cannot be opened anymore.

It keeps increasing, increasing every few seconds.
After troubleshooting, it was found to be a socket problem.
Because every few seconds, the socket function is used to obtain the IP.
It is closed using the close function.
I checked again and found that the handle was constantly being added because the close function did not completely close the socket.
