Now after multiport switch the cgwatcher cant even successfuly restart cgminer. Hope you can help me with that when you have time flound

I'm not sure man, what version of cgminer are you using, can you post your config and screenshot?

3.3.1 but the same happened with 3.5. Let me repost the miner log:

As you can see before each switch I am getting a getwork failure and then pool is going dead for me.
Moreover I was never able to successfuly mine through multiport(started 2 days ago) so the solution maybe too obvious to see.

Then cgwatcher tries to restart but cgminer just wont connect to pool as if pool was dead, or more likely rejecting my connection on purpose.

Edit to clarify: CGwatcher is able to start cgminer but it just waits at startup showing only version info. Like it was waiting for connection. Since no connection is made in 30 secs, no api is started therefore cgwatcher kills the process and starts over. If I wait a certain amount of time it will connect me in few secs(sometimes takes 2, sometimes 10 attempts).

Edit2: I am not using conf file, so there are no hidden switches that could crash cgminer. Just command line:
"--scrypt -o pool1.eu.multipool.us:3336 -u fredeq.1 -p 1xx --intensity 13 --worksize 256 --shaders 2048 --thread-concurrency 8192 -v 1 -g 2"

Looks like middlecoin missed the FTC fork and lost a bunch of blocks too.
https://bitcointalk.org/index.php?topic=259649.msg3274282#msg3274282

That's tricky, the announcement of the FTC fork was a sticky on this forum, and Bushstar told most of the exchange operators, and put it in a lot of chat boxes a week ago, I saw him do it.

The fork was a difficulty formula change to stop the wild 41% swings that were happening each diff change. It's much smaller changes now, only 9% but more frequent.

He also said it would take effect around October 1st..  It happened 2 days before that.

Anyway, I'm much more concerned with the fact that the new version is rejecting our blocks.

flound1129,

When you post here that there is a problem with a coin and you are working on it, could you also add an update to the 'news' on your website home page?

I look there first before I come to this thread and start reading backwards through the posts, trying to figure out if there is an issue and you are aware of it.

Thank you!

Also, I do think something gets skewed with DGC profitability when there are multiple blocks per minute.  I certainly do not think it is a situation of  you taking advantage of the pool.  I see I am earning a fair share of each block and when I look at how many blocks the pool is getting I think the reality of earnings is less than expected compared to 'profitability' calculated from hash rate and difficulty.  Rather than come here to accuse you of something when DGC is getting the resources of the multi-port I prefer to switch my miners to a direct port on an alternate coin.

tl,dr; When the difficulty of DGC is really low it is a disappointment to mine via the multi-port and I try to avoid it when I can.

Finally thanks for putting your time into running the pool and dealing with all the BS associated in this endeavor!

I will try to keep the site news more up to date.

As far as DGC, there was an issue with one of the pools the time zepadee posted which was causing us to not submit blocks properly for about 1/3-1/4 of the hashrate.

If you look at the last time we mined DGC, it was much better, you can see the very smooth hashrate distribution under My Stats which was much better looking than the previous one (which has scrolled off by now, unfortunately)..  The difficulty changed at block 463320, Multipool found 386 valid blocks and 19 orphans between 463320 and 464400 when the difficulty went back up.

So we found almost 36% of the total valid blocks during that low difficulty period which is very reasonable when you consider that we were at around 750 MH, Middlecoin was probably around 900-1000, and the rest of the network was probably at least 500-600.  In fact we probably found more blocks than we should have. The network hashrate graph shows a peak at 3.83 GH/sec but I don't know how accurate that is.

386*20 = 7720 DGC, in about 85 minutes

7720 * .00013 BTC/DGC (current price) = 1.0036 BTC

1.0036BTC / 750 MH/sec / 85 minutes = 1.574e-5 BTC/(MH/sec)/minute, * 1440 minutes/day = 0.02267 BTC/(MH/sec)/day for that time mining DGC.  That is 130% of litecoin or 670% of BTC profitability (assuming LTC was around 500% of BTC at the time)

So I think we're doing OK with DGC.  We don't get the calculated 1200% returns or whatever, but it's still worthwhile to mine DGC, assuming the pool is working properly.

Here is a screenshot of my cgminer connected and mining to us multiport. You can also see EU server being reported as dead. Same happens for general ltc pool.

[MickeyT2008]

The EU server does seem to be having problems.  Sometimes it won't connect, other times it only works for a while and then drops out until I reconnect it or give up and use the US server instead.  On other occasions it works just fine for hours.  I can connect to both servers but I'm not sure if I'm supposed to do that or not.  When it's working I get a lot less stale shares on the EU server because its ping is much lower as its on the same side of the planet as me

The EU LTC pool has had some issues today, things should be more stable now.

I'm going to be taking the EU pools down tonight to add another couple servers into the mix.  I will post here and on the pool news when the downtime is about to happen.

Fredeq: I would suggest setting at least one backup pool (aside from another multipool server) so that if you're unable to connect to multipool, you're at least mining something. If you have cgminer set to failover, it should switch to the backup pool and then check the first pool occasionally to see if it is alive. If it is alive, it will switch back to it. This should also resolve the problem of cgminer taking so long when starting, because it will find a working pool and continue instead of trying to use a dead pool indefinitely.

If you find that cgminer does not switch back to multipool (or any pool with lower priority number) when it comes back alive, let me know and I'll try to add options in CGWatcher to ensure this happens. I think cgminer has always done this correctly in my personal experience.

EU Pool Maintenance will begin at approximately 7:00 GMT.  The EU pools will be down for approximately 20 minutes.

[Jcw188]

I've been having disconnects on US pool the last day.  It's a random short drop but get stratum_recv_line failed, just as I have gotten for ages at this pool on 7777.  All the talk of "fixing" the stratum problem...

[TheDirtybird]

Not sure why no one has ever said anything but I feel it is time that I did .. its just a silly mistake.. but on the main page it shows what is "currently" being mined.. well currently is spelled wrong (curently) and has been misspelled for months.. it needs one more r.. not being spelling nazi or anything but it has been incorrect for a very long time..just bringing it to attention but it doesn't change anything of course..

Good luck all in this crazy October of events!!

Your post also contains spelling errors in its text.

First post here since bitcointalk is back?

Was multipool down until like just now?  Website was down, JSON feed not working and openly a few CPU miners of mine seem to still sustain as cpu miner never gives up.

Thanks

[Torn]

Things roll on. Welcome back everyone.

Be well, Happy mining!

I got an alert from the monitoring system at 5:22 am saying the website was down and it recovered at 6am.  Also had a couple of the cronjobs hang which I fixed about 20 minutes ago.  Looks like the DB ran out of connections.  The pools should not have been affected.

[girlfawkesy]

I see that there is a bitcoin pool now and people are mining on it. Whats the server address?

[flound1129]

Nobody's mining on it atm, there are some shares in the db from when I was testing last night, that's all.  The BTC pool and the sha-256 asic multiport will be launching soon.

[flound1129]

BTC pool is up on 3332.

[snamor]

I'm very excited to see the new SHA256 Pool, but I think that the auto-paymen minimmum threshold for Bitcoins should less than 1 BTC. Now I'm not able to set less than 1 BTC.
Also letting LTC and NVC minimmum auto-payments be less than 1 could be great too.

Thanks!

Yikes, yep that's a bit high for the lower Gh miners.  :/
