Latest version seems to have broken merge mining with p2pool - I've not had a single payment since upgrading it. I'll revert back to the older version to double check.

I noticed that I didn't get a unitus block for a few days but thought maybe it was just high unitus hashrate or bad luck. Please report if older version is working.

Is there any way to reduce the CPU, memory usage from new version?

It consumes too much CPU at startup and eating more than 1GB of memory during running.
Do I have to tweak some numbers?

Running 0.11.2 now, but I don't think it works either judging by the debug log, it looks the same as 0.11.3 ie no accepted blocks. Weather this is because there was a fork with 0.11.2 or simply because everyone else is using 0.11.3 I'm not sure.

I hope this isn't another case of updating a coin which breaks p2pool merge mining, which seems to be the trend lately - first NMC, then SYS, then ARG & now XMY. Soon there won't be any merge minable coins left to mine - even though they're all supposed to be...... Roll Eyes

We have observed that CPU usage will be high until at least 8 nodes are connected. Once enough peers are found it seems to settle down. Memory use is high though, and I suspect that will be difficult to limit. You could try to set a ulimit on your daemon user and experiment though... Undoubtedly more work needs to be done on this front.

OK, this isn't good.

CPU = 20-25%
RAM = 1GB+
Merge mining broken.

I think I'll revert back to the older v9 client in order to get everything working again, as I'm seeing quite a few v9 clients still in use. Can someone tell me if I'll have to redownload the entire blockchain again - or can I use the one I'm using with v11?

Thanks.

Might work now but I believe all v0.9.x clients are going to get forked off the network when new one activates.

When will that be - is it by consesus or block #?  I think the fork should be cancelled until these problems are ironed out tbh, forking the network will result in merged miners no longer being able to mine - meaning XMY losing most of its hash rate, won't it?

I'm not sure merge mining is broken, see:

http://insight-myr.cryptap.us/block/1bc76704452bae595989f60527519abcd9a718af6627a29aebe913844c4535a3

This is a sha256d block, appears to be aux-pow, and a version 4 block. That should be on 0.11.3.1

The fork will be done via consensus, 75% v4 blocks after block 1764000. But v 0.9.x can be forked before that block, if 75% v4 consensus is met.

edit: I'm keeping some status here: https://cryptap.us/myr/myrstat

0.11.3.1 miners are v4 miners

I think he was saying that merge mining using myriad as the parent coin on p2pool was broken, not the auxpow algos are broken. Could be wrong tho...

I use a few coins as the main chain: ZET, NEOS, TRC & XJO. Never had a problem up until v11.

I'm compiling v9 again now...

Edit: OK, I can confirm that when using the v9 client with p2pool merge mining I am once again seeing:

Code:
2016-07-20 00:03:21 ProcessBlock: ACCEPTED
2016-07-20 00:03:22 CreateNewBlock(): total size 1000

in my debug log, meaning everything is working fine again. Also, CPU usage is minimal & RAM usage is ~700mb, so everything is as it was again.

Whatever changes were made to XMY between v9 & v11 seem to have broken merge mining & increased resourse usage dramatically. At the risk of losing many miners & network hash rate/security - I would respectfully urge the devs to cancel the fork until the problem is resolved. I can supply any logs needed.

Merge mining is one of the many things that make XMY a great coin - to suddenly & needlessly discard it would be potentially devastating.

CPU usage is still high even I ran new myriadcoin daemon for more than 10 hours.
Surprisingly, connection count is 5 still.
This daemon's algo is set for "groestl".

Interest thing is, I have another daemon which runs for qubit algo.
I started few minutes ago, and it's connection is 4, CPU usage is quite small. Around 0.5%
I think it's normal.

I don't know the difference between two daemon, but seems like one is doing something wrong.


Here's some log from groestl algo daemon.


......erased log since it includes ip addresses......



Actually both daemon's log is similar except kepool reserve, return number.

Anyway, it's hard to maintain this kind of daemon on 24/7 server. It harms much.

Update: After running v9 over night, I can once again see payments from merge mining XMY flowing into my wallet  Smiley

I would urge anyone who is merge mining XMY NOT to upgrade, especially if you are using p2pool.

@ jwinterm: Is UNITUS using the same code base as XMY? If so, try reverting back to the v9 client also?

The CPU usage should calm down once 8 or more peers are found, please addnode some from http://myriad.nutty.one/home

Interesting though, to clarify you're saying that the Myriad 0.11.3.1 daemon using qubit is not using high cpu with only 4 peers?

I checked again and found that qubit's connection is now over 8. (I have modified net.cpp MAX_OUTBOUND to higher number)
Don't know why it consumed so low cpu at that time.

I added several nodes to groestl algo daemon manually and now it consumes low cpu.
Connection count was only 5 but increased. Maybe that daemon did have some trouble finding peers.

Seems like memory usage is the last problem.
myriad daemons are consuming more memory than even bitcoin. Is it related to multi algo structure?

That's my assumption, yes. A Myriad node has to confirm blocks for all algorithms, not just sha256d.

That's my assumption, yes. A Myriad node has to confirm blocks for all algorithms, not just sha256d.

I restarted qubit, skein, myriad algo for each coin and found that only myriad algo daemon consumes much cpu before connection count reaches 8.
Almost 100%, but qubit, skein doesn't run like that.
Maybe it's not related to algo, but only that daemon. It is really weird that only one daemon is working differently.

One more different thing is that myriad algo daemon is built from empty data directory,
while other coins used previous data directory with "-reindex" parameter. Maybe skein, qubit is using old peers.dat
Any idea about it?


I understand about memory usage but it worked with smaller memory before this latest version.
Maybe transaction memory pool allocated per algo?
Seems like some memory space is wasted, duplicated which can be shared.
