I want to report, that cpuminer found a block and I cannot see it in the "listtransactions" report... I mined Franko (FRK), GBT mode with address and no signature. I don't have cpuminer detail log but I have debug.log from frankod. cpuminer and server are running on the same PC. From the log file I have I assume it is some problem with frankod...
cpuminer:

Block founded by my cpuminer should be between blocks 741280 add 741281 but it is not there. I see
ProcessBlock: ACCEPTED but block is missing and I cannot explain it...
$ frankod getblockhash 741280

After this experience, I will mine with --no-gbt parameter...
I found similar situation when block was really accepted. debug.log is different in this case, I see message
