Hi,
What is the command of these parameters?

retry counts
retry delay
job timeout

In the case of a connection error, Gminer closes itself after some tries for the re-connection. Almost all well-know miners have these parameters. By increasing the number of retries and also increasing the timeout, the miner remains open if a connection error occurs. Please take a look at Claymore:
