I increased the RAM capacity of 1 GB and add a 60 GB disk dedicated to bitcoind.
After I launch bitcoind it begins to take a lot of RAM, up to 650 MB, and die some hours later. The blockchain is ~10 GB large and not yet completed at the moment. It already crashed two times.
The command line is the following (there is nothing in bitcoin.conf except the RPC login and password)
I'm using Debian Sid and bitcoind 0.8.5-1 i386 from the repository.
I briefly looked at 'debug.log' but it seems there is nothing helping in it.
This is very strange because when I'm using the Windows version it takes about 200 MB and has never crashed.
