yes i already built a load balancer for few bitcoind wallets, and of course they will be separated into fewer addresses. and this wallet will not grow, i will leave it as it is because i don't have idea how to split the wallet.dat easily

hahaha yes it is very silly, it turns out I was using 32bit box no wonder bitcoind crashes when reach 4gb and ignore the rest of the memory i already moved it to 64bit and everything seems to work fine. thanks for the help anyway, for anyone have similar issue but with limited RAM, using -dbcache=16 really do the trick. it works even for 100k+ addresses but every command become very slow.

is it possible to create a new wallet without resync? tried to move the wallet.dat, starting bitcoind gave me Code: Corrupted block database detected. Do you want to rebuild the block database now?

i was trying to avoid resync the whole blockchain if possible (it already takes 1 day to reach 34xxxx). but I will do it anyway. and see what happen. will update later. thanks for your help.

what i'm really confused is the server doesn't seem to run out of memory. only 3gb being used.

Quote from: CIYAM on January 17, 2016, 02:22:16 AM Quote from: buffett on January 17, 2016, 02:16:41 AM the wallet has 100k of addresses ^ That is not a good idea. The wallet doesn't scale well at all and despite the large amount of RAM you might be hitting a limit that is causing the bad alloc (although a bad alloc could also be caused through passing an invalid value for allocation). To work out whether the problem is your wallet's size back it up and then delete it and re-start Bitcoin (it will create a new empty wallet). If no crashes happen with the empty wallet then I would assume your problem is the huge wallet. i know it is not a good idea, but i need to get this wallet up. any ideas?

I'm sorry for posting in a zombie thread. Anyone looking for a solution for accepting 0 confirmation payments may check blockcypher api: http://dev.blockcypher.com/reference.html#zero_confirmations It's not mine but I think it's worth mention here since I was also struggling looking for a simple solution for this matter.

Quote from: CryptoPanda on September 22, 2014, 11:39:37 AM what do you mean by active addresses and why it becomes slow? active address i mean if the address is not empty. bitcoind is pain in the ass in large scale

This is brand new bitcoind installed in ubuntu 14.04, *bitcoind getbalance '' 0 always return same value with bitcoind getbalance ''* or *bitcoind getbalance '' 1 or bitcoind getinfo** although it has unconfirmed transactions. Anyone have a clue?

I have an exchange pretty much like btc-e. each member has their own btc address to make deposit.

Do you have any solution for handling large wallet with bitcoind? The only solution I can think is by separating addresses into few bitcoind server. let say 10k addresses per server. But this solution is not elegant and requires a lot of work. Thank you.

Bitcoin / Bitcoin Technical Support / How to make Bitcoind to run with more than 1 CPU

on: July 17, 2014, 07:45:32 PM

I have 8 core server, this server is dedicated for hosting bitcoind. So I want to utilize all CPUs for bitcoind to make it faster and more responsive. We host ~20000 addresses and bitcoind is getting slower and slower everyday. For now it takes 2-5 seconds for each transaction. From log I got 2 transactions executed for more than 60s. Thank you.
