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
