Two more questions

I am running 2 Win10 machines without GPU's. Each machine has installed the BBP wallet and the BOINC client. I am receiving regular PODC rewards but several days ago both wallets stopped mining (0% CPU activity and no rewards in 8 days). Here is the config file for the 1st machine:
addnode=explorer.biblepay.org
genproclimit=2
gen=1
externalpurse=BQ5epKDHsp9AWjVgRYd9ZysQa7g75ve539
externalprivkeyBQ5epKDH=[my_private_key]
externalpubkeyBQ5epKDH=BQ5epKDHsp9AWjVgRYd9ZysQa7g75ve539
1. Is the config file okay?
2. Should the config file for the wallet on the 2nd machine be identical (for PODC purposes) or reflect the CPK of that wallet?
Thanks!
Your config file allocates 2 threads to RandomX mining; was that intentional? Considering in-wallet mining is not efficient for RandomX, I would not allocate any threads to heat mining at all (i.e., use that power towards PODC instead)
In any case, you do not have to run multiple copies of the wallet for PODC mining - it actually complicates the matters. You do not even have to keep a single wallet open 7/24 - all you need is a stake-confirming transmission made once a day. You can do that by firing up the wallet, letting it sync, then manually perform "sendgscc wcg" in the console, and shut down the wallet.
You need to make sure your stake (collateral) matching or exceeding the required coin-age for your RAC is present in your CPK address.
Could you please check:
1. Stake requirement met in the CPK address
2. GSC transmissions made from your wallet in the last 8 days
