Bitcoin 0.14.1 client crashes and not reachable on bitnodes.21

[r1973]

Hello,

I used to run full nodes until 3 months ago. Three days ago, I re-started running a 0.14.1 full node - but problems started. I have a Win10 PC. Port 8333 is open.
the problems are:
* My static IP (141.226.3.1) is unreachable in bitnodes21. [again, port 8333 is open!!!].
* The client crushes all the time (with 64 bits software which I replaces with 32 bits version).
* I run the client for 3 days, but at most I have 5-10 active connections (both in & out) at most before it disconnects and crushes (i.e. I get a black screen) on the client and the help >> debug pop-up window
* In these three days,  I see more black-screen windows than real-time running and functing software.

I want to help the BTC network - but what can I do to solve these chronic problems.... Right now I am 7 weeks in behind the blockchain (downloading block 458047~).
 
I am thinking to delete everything - because my client doens't function/work/connect - and I am very upset about that.

Any help/advise?

Crushes? Do you mean crashes?

Can you please post the debug.log file?

What are the specs of the machine that you are running Core on?

Sorry for the spelling mistakes (I am not an english native speaker, and have these writing mistakes all the time, all my life - again sorry)

Bitcoin Core 0.14.0+ uses more RAM than previous versions, so 4 GB is not going to work very well. Try adding the following lines to your bitcoin.conf file (if it doesn't exist, just make a text file and name it bitcoin.conf and make sure it does not have a .txt extension):

Code:

dbcache=200
maxmempool=150

Then restart Core. This will reduce RAM usage so it won't crash.

thanks for the fast reply.
Just to make sure, are you talking about setting up a text file on windows (c) >> program files >> bitcoin (attaching an image for the supposed location - https://i.imgur.com/Ww2doAU.jpg)?
Is that correct?

No, it goes in the Bitcoin datadir, the same place you got the debug.log file. You can find the path to the datadir by going to Help > Debug Window in Core and find the field labeled "datadir". By default it is C:\Users\<your username>\appdata\roaming\Bitcoin

Thanks. I've added the bitcoin.conf file, but on running the program I get this black screen when client starts for the first  30-60 seconds (http://imgur.com/HYo6Nmx) - then it seems to be running ok.

On bitnodes.21.co - my IP (141.226.3.1) is reachable 1 out of the 4 clicking the "check node", and unreachable 3 out of these 4 "check node" clicks (which is an improvment, I guess). Any guesses why?

I will keep the client running for the night and check on it in 10 hours time.

Don't give to much value to what is shown by https://bitnodes.21.co , that site isn't very reliable. For two reasons:

1) it is quite buggy
2) it was subject to various attacks and attempt to skew statistics, therefore it employs various strange algorithms to defend itself and other servers on their ISP

I have very reliable connection and frequently get less than 50% availability score on that site. It isn't completely useless, but it isn't even statistically correct.

thank you for your help.

I was pondering should I continue this thread. Decided to re-ask again:
 
After a long few days, I have almost downloaded all the blockchain - but...
* the black screens/not responding/crashes on my 0.14.1 core client continue consistently, routinely (recent pic >> http://imgur.com/Ea5f9hj).
* the number of in/out connections is very low, slow, and unreachable (100% of the time) on bitnodes.21, if that matters.
* I am attaching a newer and recent debug_log >> https://files.fm/u/d949vmrd

My question is - should running my full-node makes a difference? Should I just delete the client and forget about it?

Any suggestions?

For you, personally, it would make a great difference. You would learn a great deal about computers and networking. Whether it is worth investing your time, only you can make a true answer.

1) Bitcoin-Qt's window getting black is due to the design decisions made by the Core developer's to keep the reference client tightly integrated. It is more of a cosmetic issue for vast majority of users who don't try to integrate with other financial software.

2) You computer is kinda crappy, from the vendor that is recently known to ship borderline-scam computers to meet marketing targets. Learn to make use of what you have or buy/assemble something better, even using older parts. Notwithstanding the above comment the reference Core client is quite well-optimized and serves as a decent hardware stress-test for CPU, memory, disks and their controllers.

3) Your network connection definitely seems sub-standard. Do you even have a real Internet connection or are you using some CG-NAT cheapie?

4) Avoid posting your actual IP address on this board. It is full of sharks who probably run all kinds of scans on your computer to find possible misconfiguration and steal your coins. There were all kinds of scammers offering remote help via TeamViewer (or similar tools) to rip people off.

The decision is really up to you.

1) Once the download was over (a couple of hours ago, after about 10 days), the software is running smoothly now , with no crashes at real time until now.
2) thanks. you're right.
3) I have a very good internet connection, I think.
4) I am well aware of that. My wallet is and will always be with zero bitcoins in it. Never keeping coins in it. Even if sharks attack my PC with malicious software -  I will replace my PC with a new one if needed. I will not be a victim of a scam. Nothing to steal from me. Zero balance on bitcoin core, with known IP.  Just trying to help the net. I am aware of needed Bitcoin security:)
