Bitcoin core 0.10.0 closes for no reason, no error

[Mikestang]

Bitcoin core 0.10.0 closes on me without warning, for no reason, has happened the past two days.  I don't get an error message or anything on the computer.  I get an email from Bitnodes saying my node is down, so I look at my computer and sure enough core is no longer running, it just up and shut itself down.  What gives?

Check your system's logs, it should provide information on what is happening.

[Hazir]

Op you should also ask developers in this thread: https://bitcointalk.org/index.php?topic=957509.0 And give us some more information about your issue. Mainly your operating system, does it  only happen from time to time or every time, how often? Any other weird situations with other software are present as well?

[MineForeman.com]

You should find a debug.log in one of these directories (I googled them, I don't have a windows bitcoind install);-

C:\Documents and Settings\YourUserName\Application data\Bitcoin (XP)

C:\Users\YourUserName\Appdata\Roaming\Bitcoin (Vista and 7)

You can look in there for errors.

Just because I am curious, search for "ReadBlockFromDisk : Deserialize or I/O error - ReadCompactSize() : size too large" there is a thread going on at github about an odd issue that may or may not be a bug. (https://github.com/bitcoin/bitcoin/issues/5668)

EDIT: And Hazir probably has a good idea .

You should move this thread (control at lower left) to the technical support section - you will get a lot more help there.

What are the technical specifications of your computer? Especially RAM.
I had a full node on a VPS and it was shutting itself down until I upgraded its processor and RAM.

[Mikestang]

My computer is old, built by me many years ago, it runs WinXP SP3, Intel Core2 6600 @ 2.40GHz, 4gigs ram (OS reports 2.75, blame the old OS).

I read through the debug log but didn't see anything that stood out, but there's tons of crap there.  Here's an excerpt from right before my OP, which was right around when my node went down:

I did a search for "ReadBlockFromDisk" and it turned up 0 results.

A little more detail exactly how I notice the crash.  I get an email from Bitnodes that my node is down.  I look at my computer screen, bitcoin core is minimized to my task bar; it appears to be running.  When I mouse over the icon, the icon disappears - because the program stopped running a while ago when I got the email.  Wonder if it has to do with minimize to task bar?  I'll turn that off and see.

Thanks.

You will probably be told to use a more recent OS...

IIRC WinXP works fine with bitcoin core as long as the 64 bit version is used.

My computer is old, built by me many years ago, it runs WinXP SP3, Intel Core2 6600 @ 2.40GHz, 4gigs ram (OS reports 2.75, blame the old OS).

I read through the debug log but didn't see anything that stood out, but there's tons of crap there.  Here's an excerpt from right before my OP, which was right around when my node went down:
-snip-

The log looks fine which suggests that the problem is related to your system and not the program itself. 2.75 gigs RAM shown suggests that you use a 32-bit OS, which is not able to allocate more memory without some serious (and possibly unsafe) kernel hacks. As Newar suggested -> do you have a chance to get a more recent OS or at least a 64 bit version? 32-bit Windows users have reported problems in the past, usually memory related. Others have reported that decreasing the dbcache might help. In order to change the cache settings create a config file[1] in the appropriate directory[2] and add the following lines to it:

Code:

# Set database cache size in megabytes (4 to 4096, default: 100)
dbcache=50

This might help, but the best solution IMHO is to go 64-bit. It allow your OS to use the full amount of memory the hardware provides. You are currently wasting >1Gig.

This is typical even for later Windows versions and I think I also have seen Linux do this. Its just not updating the taskbar unless it has to.

Is it just me or does other have the same problem: My bitcoin core takes 10-15 min to start up (core due 2, 2 gb ram, win7).
This is before syncing, syncing comes after. I think it was faster like a year ago, is this because of the very big bchain?
I am thinking about switching to a thin client. I guess that is enviable.

Its probably best if you either open a seperate topic or add this to a topic that at least fits your problem, e.g. here -> https://bitcointalk.org/index.php?topic=973890.0

I owe myself a new pc, this one has outlived its usefulness. For the time being I am stuck with 32 bit, hopefully by summer I'll have a new box. If this continues to happen regularly I will try the configuration option you suggested and see if that helps. Thanks.

Ok, I will do that, thanks.
I have a personal question, I have seen your name before "Shorena" are you famous for something (creating an alt coin or somehting like that?), the name ring a bell, but I cant remember? Peace.

So my node runs perfectly all weekend, no problem.  I go to work today, Monday, and just now received an email that my node is down.  WTF?  When this happened last week it was right about this time of the day.  Very curious, why does my node not like the week days?

Nobody likes Monday ... Not even Bitcoin

In all seriousness do you have the option of throwing a Linux distribution on that box instead of the ancient XP you've got now?

Yea, I could spare some hard drive space.  Does Linux need its own partition, or can I just install something like Ubuntu like any other program?  Guess I'll look into that

I have Cygwin and have used it exactly once, but I think you're saying I need a full OS.

Are you suggesting this because it would make my problem easier to trouble shoot, or just as a recommendation at large?  I know my comp is outdated and my OS is more than outdated.

I'm suggesting it because a 64 bit Linux distribution will be a far better OS choice than the no-longer-supported XP you currently have.

[Mikestang]

Had this happen 3 or 4 times since last posting, tried a few things on my own and nothing seemed to stop the random crash.  I've just now set the cache to 50 megs, will report if that makes an improvement.

It does need separate partititon. I suggest you using a ubuntu server version with no gui if you only use as bitcoin node. it will be a light and fast solution for your ancient computer. working with command line may be tricky though.

mmh i can only think of something wrong with your os installation, or maybe your cpu is at 100% when you run the client?
