HOW TO GENERATE A TECH SUPPORT LOG:

You can create a detailed log by putting the following line in your "Extra cgminer parameters" which is located under the "Settings" tab in your RPI web interface:

Code:

--verbose --monitor 'cat > /opt/minepeon/http/log.txt'

Be sure to get the single quotes (apostrophes) and spaces correct. Incorrect data entered in this box can break your system! Note that this will now be logging a large volume of text to your SD card, which is a bad idea, as it will rapidly wear out if it has to log all that data. So be sure to restore the original settings (default is blank) after your logging session.

If your log is getting overwritten too much because the session keeps dying, simply add an additional ">" to the existing one, with no extra spaces. This will cause it to append the logs instead of overwriting them.

Once you have seen the problem occur, you can access the log file at: http://ip.address.of.your.minepeon/log.txt (so for example: "http://192.168.1.101/log.txt")

If you are not sure of your IP address, you should be able to find it by visiting http://setup.hashfast.com/.

If you can then ZIP or TGZ up the log file and either email it or upload it somewhere where you can share it, such as https://mega.co.nz/, We will then be able to take a look and see what's going on.

Again, DON'T LEAVE THE LOGGING RUNNING TOO LONG! It will burn up your SD card!

Running cgminer in verbose and looking at the log, I noticed it is filled with lines like this:

[2014-02-14 01:27:12] HFA0: invalid nonce - HW error
[2014-02-14 01:27:12] HFA 0: No matching work!
[2014-02-14 01:27:12] HFA0: invalid nonce - HW error
[2014-02-14 01:27:12] HFA 0: No matching work!

So much so that the log is growing by about 500k a minute.

What could be wrong?
