I compiled bitcoind using the same steps as last year. In particular I set DB_CONFIG:
set_lg_dir database
set_lk_max_locks 537000
Unfortunately once I hit block 364,670 (2015-07-10) I'm treated with:
EXCEPTION: 11DbException
Db::put: Cannot allocate memory
bitcoin in ProcessMessage()
I tried raising set_lk_max_locks to 1000000 but that didn't help. This happens immediately when restarting the node, so it doensn't seem to be a RAM issue.
The ~/.bitcoin/database looks rather large, assuming this is the equivalent of todays ~/.bitcoin/chainstate and ``~/.bitcoin/blocks/index`.
$ du -s ~/.bitcoin
92047404 # 88 GB
$ du -s ~/.bitcoin/database
42169668 # 41 GB
How can I get the synchronization to continue?
