Mining halting, even with multiple pools listed

[korishan]

I only ever see it mining on Pool #1. I have several listed (as for me, I need to change locations for NiceHash as I get rejections from time to time)

• VERSIONS: XM Rig/2.4.3-beta2 libuv/1.14.1 OpenCL/2.0 MSVC/2017
• CPU: AMD A6-6400K APU with Radeon(tm) HD Graphics x64 AES-NI
• ALGO: cryptonight, donate=1%
• POOL Update README links and build instruction #1: xmr-usa.dwarfpool.com:8005
• POOL build error with rocm #2: cryptonight.br.nicehash.co:3333
• POOL macOS 10.13.1: Error when building (GpuContext.h implicit instantiation of undefined template) #3: cryptonight.br.nicehash.com:3355
• POOL macOS 10.13.1: No AMD OpenCL platform found. Possible driver issues or wrong vendor driver. #4: cryptonight.br.nicehash.com:3355
• POOL GPU Compute Error on macOS 10.13.1 #5: cryptonight.br.nicehash.com:3355
• POOL Hashrate / speed doesn't show for 10s but 60s #6: cryptonight.br.nicehash.com:3355
• POOL Build error: at API state #7: cryptonight.br.nicehash.com:3355
• POOL Any chance of more than 1 thread? #8: cryptonight.br.nicehash.com:3355
• POOL Only one OCL device used and detected #9: cryptonight.br.nicehash.com:3355

        {

            "url": "xmr-usa.dwarfpool.com:8005",
            "user": "WALLET.Korishan2GPU",
            "pass": "x",
            "keepalive": true,
            "nicehash": false
        },

I stays on Pool #1, then every so often, I'll get "No work found" or something to that effect, and the miner closes and I'm left with "Press any key to continue...." which of course, closes the whole console out.
So, big question, why is it not cycling to the other pools when #1 doesn't have any work for my miner to do? I thought that was part of the reason for having multiple pools so the miner isn't left sitting idle.

TIA

Press any key to continue . . .

So why didn't it automatically go over to the other pools? Isn't that the whole reason for multiple pools is to switch when nothing is active or one goes down?

    "pools": [
        {
            "url": "xmr-usa.dwarfpool.com:8005",
            "user": "WALLET.Korishan2GPU",

        },

            "url": "cryptonight.br.nicehash.co",
            "user": "WALLET.Korishan2GPU",
            "pass": "korishantalshin@gmail.com",
            "keepalive": true,
            "nicehash": false
        },
        {
            "url": "cryptonight.br.nicehash.com:3355\u0000\u0000hub.com:20580",
            "user": "WALLET.Korishan.2GPU",
            "pass": "x",
            "keepalive": true,
            "nicehash": false
        },

Actually, I just noticed there were 2 entries with extra text after the port number. I cleaned up the config file and will see if that cures the problem.

I suspect miner is crashed when stop mining, probably it can be simulated by pause/resume commands.
Thank you.

I'm also suffering from the same problem. How do we stop this?

If you can even point me to the parts of the code that you think may be responsible for this, I'll take a look at it and try to submit a PR

[alferz]

xmrig, I agree with your assumption, what I have seen is when a pool dies for whatever reason, the miner indeed does crash with a "no active pools, stop mining" message. It never fails over to any backup servers.

Is there anything that can be done to fix this? It sucks when you dont notice it crashed for several hours

[DrStein99]

Same problem here too. What is the point of adding additional pools, if they are never used? With xmr-stack, at least it will switch over, mine something else for # of seconds, then flip back. XMRIG just sits there and takes a nap and does nothing.

Have I setup .json file this incorrectly? Is a programming flaw?
