Run one more update - this should bring you to r643 (r607 is termed a "breakpoint update", which means its an update which requires a smartcoin restart before updating beyond this point. I will be making this more clear in the future, and possibly even automating the process of restarting smartcoin and continuing the update).
After this update, a restart of smartcoin should fix the problem. There is new database validation and sanity checking code in changes made after r607 which will automatically fix this issue.
Please report back and let me know how it goes
Yes, thank you. Now the message seem not appearing any more.
Sometimes I have another message in the line right after a GPU-name: <<>>
And in some rare cases, allmost if I use as GPU-MHz something above 900 MHz (using AMDOverdriveCtrl or aticonfig instead) the CPU goes up to 100% and all GPUs are changing to <<>>. In this case I found as only solution a complete reboot via putty/ssh.
If I leave it on GPU 900MHz and Mem 840Mhz this does not happen, only sometimes a single GPU is short time on <<>>.
If I do mining via script and not via smartcoin this behavior do not appear.
What does this mean and how can I prevent this?
As some people are telling that 910:840 and agression=7 is the best (refer this:
https://bitcointalk.org/index.php?topic=25798.0;all - the guy who told this has exactly the same config as I have), I would like to do that also, because he makes about 450 MH/s each GPU and I make only 350.
