Only unspent coins are kept in that database; spent outputs are
pruned.
-
+As of November 2013 all public servers operate this way.
+Please see HOWTO.md for more detailled information. The following is a
+short outline:
__________________________________________________________
-1. patch and compile bitcoind.
+1. Run bitcoind.
-Install version 0.8 or equivalent.
-Patch it with the patch distributed with Electrum.
+Install version 0.8.5 or higher.
+There is no need to patch bitcoind anymore.
+You need to run it with the config option txindex=1 .
+If you have not previously done so, you may need to reindex the bitcoind blockchain
Note: Even though Electrum's database uses pruning, you cannot use it
-with a pruning bitcoind. A full bitcoin node is required in order to
-know for each address if it has been used. Pruning occurs only at the
-level of the Electrum database.
+with a ultra-pruning bitcoind (forthcoming in 0.9 or later).
+A full bitcoin node is required in order to know for each address
+if it has been used. Pruning occurs only at the level of the Electrum database.

2. Install python-leveldb:
+Starting at Ubuntu 12.10 you can use apt to install leveldb. If you
+rather stay on 12.04 LTS you can use the backport and add
+"deb http://archive.ubuntu.com/ubuntu precise-backports main restricted universe"
+to your sources file. Install the package with:
+
sudo apt-get install python-leveldb
alternatively build yourself, see
[leveldb]
path = /path/to/your/database
+pruning_limit = 10
______________________________________________________________
./server load : view the size of the queue
+______________________
+Troubleshooting:
+
+* if your server or bitcoind is killed because is uses too much
+memory, configure bitcoind to limit the number of connections
+
+* if you see "Too many open files" errors, you may need to increase
+your user's File Descriptors limit. For this, see
+http://www.cyberciti.biz/faq/linux-increase-the-maximum-number-of-open-files/
