Hey together, i have running bitcoind (0.8.5) on Linux (64 bit, debian). I have started it via It starts to download blocks like expected, but then it dies. I dont know why. I have downloaded the binaries, didnt compiled it by my self. These are the last entries of debug.log, db.log is empty: received block 0000000000000000f853cbbd99b479dd58bf7a6b8bf25230526b86f1a4f7fea1

I think I have a solution.
I've upgraded my ram to 2 GB, now it runs.

It's a virtual machine without swap /edit I will create a swap partition, maybe that helps btw, i have 4gb ram now but look at this: PID USER PRI NI VIRT RES SHR S CPU% MEM% TIME+ Command
2512 bitcoin 20 0 1405M 997M 5876 S 116. 48.7 40:58.90 /home/bitcoin/bitcoind It doesn't rlease any ram... /edit I can't create swap file, because Parallels Virtuozzo doesn't supports swaps (in my case) It's becoming worse 2512 bitcoin 20 0 1658M 1201M 6632 S 187. 58.7 51:24.59 /home/bitcoin/bitcoind 58.7% of 2GB Ram... |

Lol... How could that eat so much? So even 2gb isn't enough? Can anyone tell me if large swap could help or if I really need 4gb ram?

Bei solchen Services wäre etwas Swap ratsam. Ein Teil des Adressraum muss nicht dauerhaft verfügbar sein und kann dann ausgelagert werden. Ausserdem verhindert man, dass der OOM Killer einem im Ernstfall einen wichtigen Prozess beendet.
Source: https://bitcointalk.org/index.php?topic=313263.msg3361156#msg3361156I try to translate: In case of daemons like bitcoin swap is advisable. A part of addres space doesn't have to be available all the time and can be sourced out. Additionally it avoids that important processes are killed because no memory is left. In my case, i can't use swap (virtual server, virtuozzo) so i have to buy more ram :-( What you can do is restart it everytime it dies. After the whole blackchain is downloaded just restart bitcoind, it will eat less ram than before. |

Cool, so do you think 1gb ram + 2gb swap could be enough? Btw how much do you pay for that VPS, where you can't create swap?

5€ per Month 1GB Ram +2GB Swap should be enough but it depends on your system, what other daemons are running, etc. Please consider that 1GB Ram + 2GB Swap will be full someday, so you have to restart bitcoind. If you're downloading the whole blackchain, this day will come fest (maybe in few hours  ). |

I have been able to run bitcoind on a VPS with just 768MB of RAM + 256MB vswap (openvz). Of course it only stays up for about a week before dying. This was with bitcoind 0.8.3. I thought they fixed this memory leak issue in 0.8.4. Anyway you can install monit. It will automatically restart the daemon if it dies.
BTW this thread is a little strange. The interaction between the OP and imrer seems a little artificial.

The basic diagram given mentioning not enough memory space for bitcoind. Bitcoind requires at least 1.5GByte memory when doing some verification even there is no GUI. Additionally, I assume you use typical hardrive like WD RED. Remember more ram the better, especially in linux due to the I/O nature.

Have you tried some online wallet to this use? Can I manage online wallet from php and all functions are the same? |

It's possible something is wrong with your virtual machine. On a clean system to run bitcoind 1GB should not cause the process to die. Check also your diskspace assigned just in case.

There is nothing wrong with my system. I have no swap (thats the main reason) and other running daemons (no clean system). Additionally there is a memory leak on bitcoind. There is no memory leak on other crypto cur. daemons like namecoind. Namecoind releases the memory it reserves. Memory usage of Bitcoind: 10% Memory usage of Namecoind: 10% 1 Week later Memory usage of Bitcoind: 40% Memory usage of Namecoind: 10% |
