Which version are you using? is it v1.0.2 ?

[slayerulan]

@cazala i am using v1.0.2

What happens if proxy loses connection with pool? Does proxy reconnect? Can I wrap the program around a script that will restart stratum proxy? What happens when miner is hashing but proxy is down? Does that mean hashes are wasted? If proxy restarts will miner eventually reconnect and submit hashes?

It'd be nice to have a HTML page that has more UI so all these details are shown on the web page. I'm using the miner UI from coinhive which is helpful... but it doesn't show accepted hashes.

I don't know of any pools that reward by hashes submitted... usually it by share difficulty and actual block has to be solved.

@sunk818 if the connection to the pool is lost, the ws connection is closed. The miner then tries to reconnect, this creates a new ws connection with it's own tcp connection and everything goes well after that. If the ws connection to the miner is lost, the server destroys that particular connection's tcp socket gracefully and everything goes well. You should run this proxy with forever or a similiar tool to restart it if it dies for some reason tho.

[sunk818]

Well Im not concerned with proxy crashing (exiting), more that it is running but in a zombie state. How would one test for this?

[cazala]

It won't keep running in a 'zombie' state, it will just exit. I need to catch those exceptions so it doesn't die, but for now you can run it with forever or other watchdog and it should work fine.

released under v1.1.2, thanks @korzhyk !
