Besides the fact OkPay is PoS coin, which could add to the number of wallet operations, it might happen this has to do with OKCash wallet being "HD wallet" - based on a newer version of Bitcoin core. Most other altcoins still use older sources, which may handle wallet IO operations differently. Do you run other coins having HD wallets?

BTW, just an additional note regarding wallets on Pi (as you mentioned you have one) - I hope you do not run wallets from SD card. Running any kind of coin wallet on SD card will eventually kill the card very quickly, so you will end up with damaged filesystem after next boot-up (regardless of it being caused by hard- or soft-reset). I have killed few SD cards that way before moving the wallet directories to external USB or NFS HDD. I don't know how you run your RPi, so this is just my advice to everyone - never run coin wallets from SD card. This means - do not keep coin directory (where the wallet.dat and blockchain files are located) on the SD card!!

Just my 2 cents...

Cheers!

OK, I will out myself as an SD-card-on-a-RPi-staker.
I am running my wallet with a SANDISK-ultra on a RPi2 24/7 for over a year and without any problems.
I do backup the data directory as a zipped tar-archive from time to time (the wallet should be backed up anyways - whether HD or SD).

The SANDISK card is quite foregiving with powerfailures - though I had only one in the last year - but no corruption of the card after rebooting.

But there are a few things, that should be done before running the wallet.:

- completely deinstall dphys-swapfile - one could only deactivate it, but after rebooting swapping would be active again.
Swapping is a bad idea, at least on an SD-card, because when your memory gets exhausted and the card starts swapping data, it only furthers the slowdown until at a certain point your wallet cannot stay synced and either shuts down or gets unresponsive and you need to kill the process. It could also get worse and your hole system gets unresponsive and you need to pull the power-plug to shut it down and reboot.
So if you would need to swap on your SBC, because memory gets exhausted, you better use a SBC with more accessible memory instead of using a swapfile.

-I use a minimal installation (Raspbian minimal for the RPi) and compile the daemon, not the qt-wallet.
Lesser processes means lesser read/write cycles.

-When starting the daemon, I use '-printtoconsole >dev/zero'. There is ofcourse no log at all, but that is exactly what I want anyways.


I do not intend to give advice to run your wallet as I do.
I just want to say, that I will continue running my wallet from SD-Card. If you are running from a HD, there is barely an advantage in using a SBC over a PC, because power consumption of your HD will probably be more than double the consumption of your SBC.
So you could as well use a PC for staking.

Thanks for reading,
 

Really excellent points. I agree 100%. Tried to use '-printtoconsole >dev/zero', but I need those logs, so turned them back eventually.

Then again, Sandisk cards are the best cards on the market, period. We didn't test all brands for sure, but have tested many and Sandisk is unmatched. You will run Sandisk much longer than any other brand, before it gets corrupted.

One question though - it looks like you run only one staking wallet on that SBC - that may be the reason why your card is still working after a year. I tend to run as many wallets as RAM/Storage allow - at least 4 per device, and that could contribute to the SD card damage.

In any case, my conclusion after several tests is the following: if someone runs many staking wallets, the most economical and safe way is to run many SBC's connected to a switch, where you also have one SBC with relatively big HDD connected and shared via NFS. You will run just a single HDD (power consumption is pretty low for a single HDD, or moreover SSD), but can run as many staking wallets as you want.

Good to hear!

You'll love the meme's we came up with today.  Looking forward to meeting the new team

Hello! and wonderful to hear!
