 __'''Error description:'''__

 After around 1 or 1.5 days the tor socks proxy is getting unresponsive.
 There is actually no error message from tor itself. Only nyx is claiming
 to not have available buffer (error 105) and does not start any more.

 __'''Error message: '''__

 `nyx -c .nyx/config -i 9951`

 `Unable to connect to 127.0.0.1:9951: [Errno 105] No buffer space
 available`

 __'''Workaround:'''__

 I could solve the problem by deleting the ~/.tor folder and restarting
 tor.

 __'''Environment:'''__

  * 2 CPU VPS with 4GB RAM
  * Tor version 0.4.2.5 build and installed from source[[BR]](also seen
 this behaviour on CentOS 7 repo package of tor v0.3.5.8)
