Are my solo mining settings good?

Ok, so expiry 15 secondes and scantime I keep it to 60 or I will have to change it too?

Try to change expiry only and look into bitcond's debug log how often it checks for the new work. The work expiry logic by Luke is quite complicated so I don't wont to get clear understanding

It doesn't look for new blocks now I think, the last block I got is over 20 minutes ago...

bfgminer wont start with -s option :/

EDIT: I retried without the -s and I think it's all good, got new block detected after 6 minutes, Thanks
