cronjob does not finish #38

Closed prdatur closed 10 years ago

prdatur commented 10 years ago

Sometimes it happens that the cronjob never ends. Need to be fixed.

Maybe the issue was that the connection to the rpc client was sometimes broken. Have pushed a new semaphore and a retry feature, so we will see if fix the issue.

There is some progress here, now I see the error not being able to connect to the RPC Client. What I see on my miner when this happens is a soft-hung miner process. It is like the RPC client gets hung trying to communicate with the miner API.

Looking at the screen of the rpc client I see the frontend repeating queries for pool information, however the miner screen is frozen, but does respond to a "q" and then hangs as defunct, resolution being a manual 'coldreboot -f'. I suspect the frontend is not getting results from the rpc client and rpc client is getting a connection to the miner API, but no reply in a timely fashion to its pool queries. The hang condition is then not being detected, and the rpc client non-responsive to a reboot/stop/start command.

After running 3 days without an error i assume the problem has gone with the latest fixes.

Reopen - whatever was happening in sgminer did not happen until now, but captured the following error from the phpminer_rpclcient screen:

PHP Warning:  socket_recv(): unable to read from socket [11]: Resource temporarily unavailable in /var/www/phpminer/phpminer_rpcclient/includes/RPCClientConnection.class.php on line 182

Hope that helps!
