For some reason after about 4000 shares in total and ~200+ rejects I get this sort of wave of rejects (hash-stale) which goes almost for 500+ rejects straight in a row or sometimes even the whole process of searching shares just freezes and nothing going on for a pretty long time! When this happens, the only thing that helps is closing cgminer .bat and reopening it again then I get accepts again... Any idea what it could be ? Is pool going to switch to stratum any time soon ?
P.S. and holy I found a block right after 10-20 minutes of my 1st mining on a pool
PP.S. 10:36pm -8 PST... the whole pool went down.
this afternoon, we upgrade the background program to improve the IO and raised the shares difficult to reduce the traffic communication with server.
so perhaps which made some rejects in about several minutes.
but now all should be ok now!
