Bitcoind daemon synchronizing error on VPS(debian)

[Ervin]

I have bitcoind installed on a VPS debian server, i started running bitcoind 2 days ago for syncronizing with bitcoin network but i got the following error today.

Code:

        root@vps:~# bitcoind getinfo
    {
        "version" : 32400,
        "balance" : 0.00000000,
        "blocks" : 258354,
        "connections" : 9,
        "proxy" : "",
        "generate" : false,
        "genproclimit" : -1,
        "difficulty" : 112628548.66634709,
        "hashespersec" : 0,
        "testnet" : false,
        "keypoololdest" : 1397553052,
        "paytxfee" : 0.00000000,
        "errors" : "EXCEPTION: 11DbException       
\nDb::put: Cannot allocate memory       \nbitcoin in ProcessMessage()       \n"
    }

I have no idea what this error mean, or how can i resolve this kind of error.

Your VPS doesn't have enough memory. You'll need to upgrade.

[Ervin]

well, i really don't know .. maybe there is another problem.
 Last week i run bitcoind syncronization on my personal computer(over windows) with  lower configuration than my rented  VPS, and I did't get such error.

How much RAM does the system have?  You may be able to enable swap on the machine and fix the issue if you can allocate a few more GBs in swap space.  As mriou says, this is a memory issue.

e.g.
swapon /var/swap.img

once you've created the swap image file.
[edit: see https://wiki.debian.org/Swap  ]

You might also be able to decrease the number of connections which I've heard may decrease memory usage.  I haven't tried that, I just make sure the machine has enough memory with some swap space too.


This should probably be in the tech support thread too, btw.

The part highlighted also looks odd.  You may want to download and build from github because that version looks really old.

Did you by any chance do an apt-get for bitcoin?  iirc that version is way out of date.

i don't have any swap area on VPS.

[Ervin]

I tried to create swap area but unfortonetly i haven't right to create.
I got the following error "swapon: /swap: swapon failed: Operation not permitted"

Is there any another solution, or i have to discuss this problem via VPS hosting administrators?

"RAM" isn't enough. I mean, I have an openvz VPS with 4 Gb "RAM" but when examining the file /proc/user_beancounters I find some draconian limits that make it difficult to run bitcoind. You might be in a similar situation. There's more than "RAM" to it.

[dewdeded]

Set "maxconnections" to 10 or 8 or 5. The highest number it wont crash with.

Given that the error is "Cannot allocate memory", it is memory issue.  You'd have to ask the admins or switch to a different provider - digital ocean has some nice options, btw. 

As I, and someone else said above, try limiting the connections. 

Also, as I said above, check the version - the current is 0.9.1 and your version is showing 32400 which is 0.3.2.4 iirc.  The newer versions may handle memory better.

Well i must talk with administrator, but before it, i would like to try this solution:

Set "maxconnections" to 10 or 8 or 5. The highest number it wont crash with.

where can i  configure bitcoind's max connections? (maybe in boitcoind.conf ? )

I got this same memory error, get stuck at the same block, and have the same version 32400.  That is however, the version installed from the bitcoin ppa:bitcoin/bitcoin

Yeah, don't use that.  It is ancient.
