I think there may be a problem with the network, please try to run with log-level 2 to see if any hint:
sumokoind --log-level 2
Some ppl reported that reducing "block-sync-size" could help in some cases, so pls try with:
sumokoind --block-sync-size 20
Is the log save in a specify directory?.
i want to show, its appear a lot of information quickly.
But i think with sumokoind --block-sync-size 20 is working better.

The daemon will start synchronizing with the network. It may take up to several
hours.
You can set the level of process detailization* through "set_log" comman
d*, whereis between 0 (no details) and 4 (very verbose).
Use "help" command to see the list of available commands.
Note: in case you need to interrupt the process, use "exit" command. Otherwise,
the current progress won't be saved.

**********************************************************************
You are now synchronized with the network. You may now start sumo-wallet-cli.
Please note, that the blockchain will be saved only after you quit the daemon wi
th "exit" command or if you use "save" command.
Otherwise, you will possibly need to synchronize the blockchain again.
Use "help" command to see the list of available commands.
