bitcoin-0.9.1-linux downloading blocks help needed please

[bitcoins_vendor]

I really need some advice, i have downloaded "bitcoin-0.9.1-linux " unpacked it to home/user/bitcoin-0.9.1-linux/ and I have created "bitcoin.conf" and saved it to "home/user/.bitcoin/bitcoin.conf" and all works as expected and it begins downloading blocks.

the problem is it takes 24hours to get to 200,000 blocks then it dramatically slows down taking another 5 days to reach 250,000 (im guessing slow down is caused  by the blocks size increasing)

so i wait 5 days and get this error (its not a one off ive tried 4 times)

"EXCEPTION: 11DbException DB::get: Cannot allocate memory bitcoin in ProcessMessage()"

there is tons of disk space (500gb with 21% used) so what is the problem? its driving me nuts with the 5day wait to fail at the last moment

as the error message says, you're out of memory, as in RAM.

Really Wow there is 16gb in this machine i never would of thought that.... dont think ive got any room for more board is maxed out

there must be something else chewing it all up bitcoind shouldn't use 16gb surely?

thanks for the reply, im trying a new approach now, I have the torret downloading.

try monitoring memory usage with htop/top to verify memory usage when it crashes.

Could you post the contents of your bitcoin.conf file.  (Probably not relavent, but might as well)

Seems to be a memory problem.
You can use windows.
