uv__io_stop: Assertion `loop->watchers[w->fd] == w' failed.
Today I got the below error and then XMRIG Proxy Aborted.

`src/unix/core.c:932: uv__io_stop: Assertion `loop->watchers[w->fd] == w' failed.`

The proxy was running fine for last few days. The hashrate was stable and everything looked normal. Until it suddently got aborted with the above error.

Now I have restarted proxy and it is again running fine.
