Well, I've been running the Windows client for about 5 days and have encountered some bugs. They are all the same for all 3 released binary versions and didn't improve in any way. Just want to summarize the issues for the Windows build:

1. Sync problem

After starting the client it can't sync ("No block source available"). Reproduced behind NAT. Sometimes you simply have to wait 10-30 min. and it syncs. Sometimes it doesn't. Adding lots of nodes from this thread to the memorycoin.conf file seems to fix this issue.

Also sometimes the client appears to be synced but the block count is less than real block count. Improves after some time or after restart.

2. Program crash

Usually happens when you turn mining on and off several times or change thread count. For example: Mine 4 Processes -> Mine 2 Processes -> Switch Mining Off -> Mine 4 Processes -> crash. I noticed that you have to wait for some time for mining to actually stop before enabling it again but it doesn't prevent crashes. Sometimes the crash is followed by database corruption.

3. Database corruption

Happens after number 3. After starting the client it shows a dialog like "Do you want to rebuild index?" Then it reindexes the database.

4. Mining stops

After mining for some time it stops. Enabling mining with any number of threads doesn't work even if the blockchain is in sync and with correct block count. Restarting client fixes this.

5. The application doesn't close

Usually happens after number 4. After closing the client window memorycoin-qt.exe can still be seen in the process list.

Thanks! It's very helpful to get detailed bug reports like these. Do you have an address for tips?

i left my miner running yesterday after the update to 0.8.54 when i returned today the miner had stopped being responsive to commands and it had lost sync with the network at somepoint yesterday.

upon closing and restarting it said i needed to recompile so i deleted all in the appdata folder and tried to resync

i tried reloading but no connections found in about 5 mins so i restarted a couple more times then just left it open ...

after about 20 mins of no connections and it being 3 days behind i have just seen it change i have 2 connection and its resyncing slowly in case anyone has had same problem you just need to be patient it will resync slowly

Hopefully i will be back on soon hunting for my first reward

[reaxion]

I need to add i also had manually to cancel the process of the MemorycoinQt in task manager to restart it

Glitch when restarting after crash. Happened twice. had to clean the block chain and chainstate folders and rebuild to fix.

[reaxion]

mine keep stalling at 2 days to go - no block source
also when my memorycoinqt starts its already mining with 8 processes so i have to stop it.

it was all working great till the updates other than major difficulty jumps

anyone know of a solution ?

Same here- deleted the old block chain and takes forever to load the block and crashes... exact same operation on the linux box and it was up and running in a few minutes.

Well, I've been running the Windows client for about 5 days and have encountered some bugs. They are all the same for all 3 released binary versions and didn't improve in any way. Just want to summarize the issues for the Windows build:

1. Sync problem

Also sometimes the client appears to be synced but the block count is less than real block count. Improves after some time or after restart.

2. Program crash

Usually happens when you turn mining on and off several times or change thread count. For example: Mine 4 Processes -> Mine 2 Processes -> Switch Mining Off -> Mine 4 Processes -> crash. I noticed that you have to wait for some time for mining to actually stop before enabling it again but it doesn't prevent crashes. Sometimes the crash is followed by database corruption.

3. Database corruption

4. Mining stops

After mining for some time it stops. Enabling mining with any number of threads doesn't work even if the blockchain is in sync and with correct block count. Restarting client fixes this.

5. The application doesn't close

Usually happens after number 4. After closing the client window memorycoin-qt.exe can still be seen in the process list.

please post your debug logs so that the devs can fix asap.

Seems like people are still having this issue of getting stuck.  Here's my solution hope it works for you.

1) make sure you have latest build v0.8.54.0-unk-beta
2) if you're getting stuck per se, go to the the path where the appdata is contained.  in my case it's C:\Users\abuchanan\AppData\Roaming\MemoryCoin so yours will most likely be C:\Users\[WINDOWS_USERNAME]\AppData\Roaming\MemoryCoin
3) Go and delete everything in there except wallet.dat and peers.dat
4) start up the memorycoin.exe again and let it sync back up from day 0 to now.
5) should be fine after this, if not addnodes...add more nodes...oh an keep adding nodes wait a bit and you should be okay.

So I had download the update for a fork at 7xx(can't remember what it was) and thought everything was fine. Didn't notice that you had decided to emergency fork it at 607.

Came home yesterday and was excited to have finally found a block. It wasn't real, though.

How was I supposed to know that you would decide to fork it 100 blocks earlier......

I'm really disappointed in this coin. I've been mining since the release and I'm done.

These are some of the pains when adopting a new coin, early bugs.

I know, I know. I just can't keep running my friends' computers (with their permission) at full blast only to find out it's gotten out of sync with the blockchain or that a new fork has been released immediately. I don't have the time for it. I think I'm still going to keep working on making a working Mac client that I can release for those who would be interested. I wish I knew more about miner development so I can help out with that.

i can confirm all of these issues, too

Yes, this is the right solution. Already on www.MemoryCoin.info, see "does't sync after update?"

Everybody, please follow these instructions.

i am back mining thanks for your help !

Although this may be a memory leak. I haven't checked my daemon's resources before the crash.

HOW annoying all crash issue fixed just fking SYNC not? No sync 3days ago fking wallet, i delete many time roaming folder etc but nothing... CAN u fix it??

Sorry man. Do you have any other client connected right now? Run getpeers and add those nodes to the client that doesn't sync. I've setup some nodes for people, but they don't keep that many connections for some reason Our new CNO will look into creating better nodes.

Everybody who wants to upgrade, listen! Do not delete peers.dat so after upgrade you can reconnect quickly.

[giveBTCpls]

Considering I mine at 0.4 kh I gave up on solo mining since its impossible.
When will poor people will be able to get some coins? when are the pools coming??
