Bitcoin Core 0.13 freezes Ubuntu 16

[achow101]

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.

Try closing as many other open applications to free up as much RAM as possible

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

Here is screen photo from latest freeze with HTOP data (sorry, bad quality):

Looks like all 4 cores are almost fully used.

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!

Okay great, dbcache just tells bitcoin t use only 500mb of cache. HTOP should show less load now, and cpus must be mostly free.

Problem solved, thanks everyone!
