I'm trying to run a bitcond on a server, it works for a few minutes and then terminates. In the debug.log is this:

$ tail -n 100 .bitcoin/debug.log 2017-04-16 14:08:21 UpdateTip: new best=00000000000001be50cb57da885f3e903b0fe3d129fd432432dss height=212484 version=0x00000001 log2_work=69.172817 tx=9974943 date='2012-12-17 06:37:20' progress=0.046851 cache=138.3MiB(350817tx) 2017-04-16 14:08:21 UpdateTip: new best=00000000000004c0432h4338907632h6fbd297203026966d862160e39a0e802ea7 height=212485 version=0x00000001 log2_work=69.172848 tx=9975073 date='2012-12-17 06:59:11' progress=0.046851 cache=138.3MiB(350839tx) ..................... 

What can be an issue? In the config I have "-daemon" set.
