Re: [ANN] MemoryCoin 2.0 (MMC) - Emergency Fork - Block 607 - 0.8.54
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.

I had all of this issues, Windows 7 64Bits.
I gave up mining in a desktop Phenom II X6, 2 days without mining QRK to get some MMC, but i left mining a laptop i5-2540m, and after deleting, installing, adding nodes, deleting again and again.... finally it found a block. With all the issues I've had, I'm feeling like winning a small lotto price
I still have faith in this project. Freetrade seems to be a men who really wants to make a good cryptocoin, different and useful. He seems to be making huge efforts to make this work, so come on! Don't lose your faith. If my laptop suceeded, you'll get your MMC soon.
