Those who have over 180mhash, do you get stratum disconnects? #36

Closed litecoinmessiah closed 11 years ago

What could be causing this issue?

I tried adding a SSD drive in the end after doing the following:

I was able to support 100+mhash with without disconnects but anything close to 120mhash or more i got disconnects at share diff 31.5

then i doubled it to 63 and managed to get 175 or so mhash without disconnects.

But stratum gets disconnected, i mean miners get interrupted.

Also added 1 backup rpc, just want to get to the root of the issue here

Likely database load. Maybe it is flushing too slowly and the shares are queuing up, eventually leading to a large dump and possibly a disconnect.

A few questions below to isolate the issue.

What is the server load like? Do you see it spike at times? Has the database been optimized (https://raw.github.com/major/MySQLTuner-perl/master/mysqltuner.pl)? Do you see anything in the logs at the times of disconnects?

@litecoinmessiah Any updated on the questions above?

Well i think it might just be the database load, i do have an ssd now which seems to have solved the problem but i still see my larger miners (17mhash or more) report there workers getting disconnects,

I will be testing out the vardiff soon and reporting results :)

@litecoinmessiah That is great news. I'll close this out for now.Reopen if you have issues in the future.
