Thanks for you attention.

Hi, please remove the --daemon option from the config. The ntopng service will automatically read /etc/ntopng/ntopng.conf on startup. Can you try to manually start ntopng from command line and get a backtrace of the crash as described here? https://github.com/ntop/ntopng/blob/dev/doc/README.crash

Hi, thanks for your asnwer. I removed --daemon option from the config, but error message still on console.
On the other hand, here the output from gdb:
