Transmission Fail to start using service

I installed transmission-daemon by follow a tutorial, and s3fs as its completed folder. At first, it came a error about failed to set buffer, after I search over web and disable the utp, but it started to fail with another reason. sudo service transmission-daemon status give me the following error:

● transmission-daemon.service - Transmission BitTorrent Daemon
   Loaded: loaded (/lib/systemd/system/transmission-daemon.service; enabled; vendor preset: enabled)
   Active: failed (Result: signal) since Tue 2016-04-19 23:29:09 UTC; 31s ago
  Process: 7045 ExecStart=/usr/bin/transmission-daemon -f --log-error (code=killed, signal=ABRT)

   Status: "Idle."

Apr 19 23:29:09 transmission systemd[1]: transmission-daemon.service: Failed with result 'signal'.

However, the transmission-daemon will start with no problem if I run transmission-daemon -f --log-error --log-info --log--debug. Moreover, if I use service command to start it, the access permission will change from 770 to 300, reason unknown. Can someone help me to solve this problem.

NOTE

The machine I'm using is Ubuntu 15.04, enabled TCP-LP, hosted at Vultr
