How To Fix (exit code=0) waiting to cool down a bit {When Dual Mining}

Today I went to setup dual mining ETH + TON on my HiveOS and I got the error (exit code=0) waiting to cool down a bit.  I tried many known fixes but none of them worked.

I was using Gminer and then tried many other miners including LOLMiner and Teamreadminer, Then I found the setting which was causing the issue, So what was the fix?

To fix (exit code=0) waiting to cool down you need to go in to the active HiveOS flight sheet and edit the Dual Coin settings and make sure there is only one connection to the mining pool.

Below is a screenshot I took of the error.  The error would appear as soon as the miner starts and will cause the miner to not start.

How To Fix (exit code=0) waiting to cool down a bit

Listed below are all the fixes I am aware of for this issue

1. Edit Dual Coin settings

This is what fixed the issue for me.

1. Go to https://the.hiveos.farm/ and log in
2. Go to the flight sheet you are using for dual coin
3. Under the dual coin click on configure pool
   
4. Now make sure that there is only 1 server selected
   
5. Click Apply
6. Save your flight sheet
7. restart your rig

2. Change Miner Version

In some miners they have a bug that is causing this error, I recommend you change miner versions before trying anything else.

1. Go to https://the.hiveos.farm/ and log in
2. Go to the flight sheet you are using for dual coin
3. Click Setup Miner Config
   
4. Under version it should default to “The Latest” change this to a previous version
   
5. Click Apply settings
6. Save your flight sheet
7. Reboot your rig
8. If you are still having issues try another version number

3. Change Miner

It is possible that the miner you are using has a bug and simply will not work for the coin you are mining.

Try switching to a different miner to see if this resolves the issue.  When switching to a new miner HiveOS needs to download and install the miner so give your system 10-15 minutes to complete this process.

4. Mixed Cards In Rigs

If you have mixed cards, AMD and Nvidia in your rig try to remove one type to see if this resolves the issue.

5. Upgrade HiveOS

When you upgrade HiveOS it installs the latest version of the miner you are using.  It is possible that in the later version of the miner there is a fix for the (exit code=0) waiting to cool down a bit error.

6. Re-Install Miner

By re-installing a miner on hiveos will refresh the settings of the miner which could help.  You can do this by using these commands.

1. Start Hiveshell in the browser or via the console
2. run the following commands
3. miner stop
4. apt remove -y hive-miners-*
5. miner start

7. Disable DAG Verify

When a miner starts it needs to verify the DAGs on your GPUs, If you have a lot of GPUs in your system this could cause an issue in systems with not a lot of computer memory in them.

To disable the DAG verify check on startup do the following

1. Go to https://the.hiveos.farm/ and log in
2. Go to the flight sheet you are using for dual coin
3. Click Setup Miner Config
4. In the “Extra config arguments” section enter the command to disable the dag verify (Different on each miner, on LOLminer it is –disable-dag-verify)
