Docker `docker0` dies several times (` inet addr` disappears)

I am running Docker version 1.4.1, build 5bc2ff8on Ubuntu 14.04. When I am docker runany container, after a few minutes my bridge docker0dies and the container ceases to be able to reach the network. Before the connection freezes, a start ifconfigtells the device docker0with inet addrhow:

docker0   Link encap:Ethernet  HWaddr 56:84:7a:fe:97:99  
          inet addr:172.17.42.1  Bcast:0.0.0.0  Mask:255.255.0.0
          inet6 addr: xxxx::xxxx:xxxx:xxxx:xxxx/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          [... etc.]

But after the connection freezes, it ifconfigshows that the ipv4 address is gone:

docker0   Link encap:Ethernet  HWaddr 56:84:7a:fe:97:99 
          inet6 addr: xxxx::xxxx:xxxx:xxxx:xxxx/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:8116 errors:0 dropped:0 overruns:0 frame:0
          TX packets:15995 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:2444859 (2.4 MB)  TX bytes:17440729 (17.4 MB)

Restarting docker, for example. s sudo service docker restart, it returns the device back, but all my containers die, and the problem starts again. I cannot reliably get anything to work for more than a few minutes at a time. Not enough to complete docker buildfor most projects.

I had the same problem and the main reason was wicd. Duration:

sudo service wicd stop
sudo service docker restart

... should do the trick.
