I suspect there is something wrong with the last version.
Running Intel Ivy and Haswell.

I do not say that it isn't finding any blocks.
But sometimes even six hours without a block, and even when periods with hashrate lower than 5 Mh/s were present.
Average spacing between my found blocks should be around one hour.
(I understand, that I will not get the blocks regularly, but if there is say four-five hours gap, then next blocks should came faster, to make an average result equal to the computed average.)

Nothing for six hours on more computers at once, is not normal IMHO, especially if I have experienced this strange behaviour more times, and everytime on majority of my computers. (I run from three to five wallets.)

Everytime I stopped the new wallet and started the older one, it really begun to deliver found blocks "immediately".
By "immediately" I mean the average rate counted from say three or four hours period is really as expected.

Is this really normal?

Thank you in advance.

Andy
