CROC pool still freezing https://cryptohub.online/pools/
CROC miners! share hashrate to some another pool, CROC wallet is not able to submit 5 blocks per minute. Commonly a pool should not have more than 50% of net hashrate
I think we need check what passes on block submit, it doesn't write to disk, but freezes, so that process takes a lot of time

What is the date of ICO?
ICO? There is no ICO. This is not a product we are selling. This is an ecosystem and currency we are developing. You either use it or don't!

Awesome work digging up the problem and implementing that solution. I'm going to make that change in my copy of that file now too...

It makes few sense if you wallet.dat is small. Actually I didn't implement anything. The dev (when he will exist) should add launching parameter to manage that wallet flushing interval
Like I said, we are going to migrate to newest Peercoin code whenever we can. I wonder if this option has been added up there?
What is average block time in Peercoin? Seems 10 minutes, so they don't need this option
I thought it was Anti Bitcoin not peer coin code.
We will not be using Peercoin's block time but CrocodileCash's original blocktime. It will embody all the features CrocodileCash has now but in a newer, compatible code base.
Yes it's based on Anti Bitcoin, which is based on Peercoin. Anti Bitcoin has not been touched in years, and so is no good to us.
I will personally add a command line argument to support the flushing if needed.

Yeah 
that is I call a success
After setting wallet.dat flushing interval 200 seconds for CROC and Q2C waiting I/O in average is only 5% now (were 60%), CROC wallet responds all commands immedeately

Nice!
My only question is, what does this imply? I think this will take more RAM.
Don't think so. It keeps wallet data in memory anyway, only writes it to disk with different interval
Actually all wallets do this shit, but on coins with large block time and that has few pool blocks wallet.dat is not so heavy
That flushing wallet.dat to disk after every block was creating in bitcoin with block time 20 minutes, on modern coin with block time 1-2 minute, especially on CROC with ~15 seconds it should be reworked. It has no sense rewrite that file if there is no new tx in that new block.

I see in log file such strings all the time:
If I use "top" command I see
61.6% waiting of I/O it's a lot, so disk is really overloaded.
This can be reason of slow work and how to resolve the problem? To have separate disk/server for every coin?
command "iotop" that shows I/O waiting processes shows me that CrocodileCashD and QubitCoinD - 2 coins with 30 seconds block time (Croc even worse since it has PoS), so no idea what to do with that coins
For now I'm going to delist qubit coin
Searching in internet give me no solution. Actually it is not a common thing when PoW, PoS and deposits (addresses generating) work on the same wallet

Yes, you need to give it its own disk then...Lots of random access all over the place when you are running many coins
I understand, but it is not good solution. It will be impossible to have dedicated server for every coin daemon.
There is a discussion about same problem https://bitcointalksearch.org/topic/problem-with-a-lot-of-hdd-writes-on-big-walletdat-1242364
Maybe there is a way to increase interval of writing file wallet.dat to disk ? If I set 20 minutes instead of 1 minute (seems so for now) I think problem will be resolved.
I don't see any reason to write it so frequently.
Let's find in code something about that
found in code:
walletdb.cpp line 559
Quote
if (nLastFlushed != nWalletDBUpdated && GetTime() - nLastWalletUpdate >= 2)
so it wants to write to disk every 2 seconds.... such a shit... let see if problem resolves if I set here 200

CROC at cryptohub works again. after sync from zero seems a little faster. I will get wallet.dat from server and try at local machine so I will know if problem is large wallet.dat or another thing

OK good to hear.
"little faster" - you said up to 90 seconds before. What does it seem to be now?
time /root/CrocodileCash/src/CrocodileCashd getinfo
real 0m41.782s
user 0m0.008s
sys 0m0.000s
time /root/CrocodileCash/src/CrocodileCashd getblocktemplate
real 0m7.318s
So all methods delay too much and wallet can't submit valid block from stratum. No way to mine it here
