Topic: Bitcoin Core 0.13 freezes Ubuntu 16 (Read 1824 times)
Problem solved, thanks everyone!
Okay great, dbcache just tells bitcoin t use only 500mb of cache. HTOP should show less load now, and cpus must be mostly free.
Here is screen photo from latest freeze with HTOP data (sorry, bad quality):

Looks like all 4 cores are almost fully used.

Okay but please add to the bitcoin.conf the settings i mentioned above,restart bitcoin, and it shall have no problem then.
ok, I have
dbcache=500
par=1
Now it adds new blocks slower of course, but hopefully it won't the freeze the computer anymore.
Can you tell what does dbcache=500 exactly do?
Thanks a lot!

Thanks for the info. I would recommend :
dbcache=500
par=1
Parameter "par" tells bitcoin to limit the threads to 1, since HTOP indicates that all of the CPUs are being busy 100% with bitcoin having 4 threads. So if we limit it to 1, plus decrease RAM then it shall work. Please try it and let me know

I did this but it froze again after about 20 mins.
Maybe there are bad blocks on HDD? Computer is new so I thought that was unlikely.
I think you are running out of RAM. Look at your CPU, RAM, and disk usage stats while you are running Bitcoin Core. I think that you will see your RAM usage go to 100% and then the computer freezes. Maybe there are bad blocks on HDD? Computer is new so I thought that was unlikely.
Try closing as many other open applications to free up as much RAM as possible
Bitcoin Core just froze Ubuntu again, it had been running for about an hour, more often it happens after 15-20 minutes. I was able to download blockchain until 1 year 40 weeks were left, then this problem started.
I can't find bitcoin.conf, it should be in /home/username/.bitcoin/bitcoin.conf , but it is not there.
UPDATE:
This is Bitcoin-Qt.conf file from /home/username/.config/Bitcoin :
Code:
dbcache=200
This should lower ram usage. The sync will go slowly, but it hopefully won't freeze your computer.Maybe there are bad blocks on HDD? Computer is new so I thought that was unlikely.

Bitcoin-Qt.conf is not related to this. That is an internal Qt thing. The bitcoin.conf file in ~/.bitcoin does not exist unless you create it. Make a new text file and save it as ~/.bitcoin/bitcoin.conf. Then add the following line:

Memory and iotop seems fine, but is bitcoin running for few minutes before it crashes? Also share you bitcoin.conf(we want the "dbcache=" variable) file please. Also, print screen your HTOP or TOP -c command output

4GB RAM? Sounds extremely low, please start bitcoin again and before it crashes run free -m , also install iotop and run it and make a screenshot. I don't think that its HDD, mostly RAM, and maybe CPU. If you want to understand better about CPU and processes download HTOP which is easier to use for non-experienced users. I would say most probably its CPU+RAM and maybe you will need to give bitcoin process lower priority and disable memory cache so that it doesn't crash the whole system
Thanks for the answer.With free -m I get this:
total used free shared buff/cache available
Mem: 3850 1799 275 93 1775 1679
Swap: 3995 188 3807
Does that mean almost all memory is used? Only 275 MB free.
"maybe you will need to give bitcoin process lower priority and disable memory cache so that it doesn't crash the whole system"
How do I do that?

Now Bitcoin Core totally freezes Ubuntu after downloading 3-5 days' worth of data.
It is actually downloading blocks quite rapidly until it freezes.
CPU usage for bitcoin-qt while it is working is more than 300% most of the time according to "top" (Pentium N3700 has 4 cores).

Thanks for the answer. Laptop is new, so there is essentially 500 GB free space, basically I don't have anything else on that laptop .
I figured out that maybe that freeze was due to overheating, because that freeze happened after laptop was already working on blockchain for several hours.
I will try to find debug.log file and post it.

How did you partition the disk?
How much do you separate? To / home directory
Switch to root account
You have tried the following commands.
Write the output on this subject.
fdisk -l /dev/sda
df -h
find / -name ".bitcoin" -type d

When I try to view debug.log I get this:
There was a problem opening the file “/home/l5/.bitcoin/debug.log”. The file you opened has some invalid characters. If you continue editing this file you could corrupt this document.
You can also choose another character encoding and try again.

What should I do?

And there is lot of text - should I just copy/paste it here?
Yes. If it is too much for here, copy and paste it into a new paste on http://pastebin.com/ and post the link. If it is still too much for that, just paste as much as you can from the bottom of the file.

If it is still too much for that, just paste as much as you can from the bottom of the file. The Bitcoin blockchain is much larger and requires more processing power to process than most altcoins.
How much free space do you have on that hard drive before you started Bitcoin Core?
Can you please post the debug.log file?

It looks like the problem is not due to overheating after all because now it occurs after relatively short period of time and laptop doesn't feel that hot.
