Yandex Server: Start indexing... Aborted

I know, that unix style is to avoid writing anything unnecessary.
Issue "dd if=/dev/sda1 of=/dev/sda2 bs=32M" and wait for 40 minutes without any diagnostics. In FreeBSD it is sometimes better - at least, you can hit Ctr^T.
But Yandex server is awsome:

# yandex-server --indexer -r /usr/local/etc/yandex/yandex.cfg

It turned out that container with Yandex Server just had not enough allocated memory... After increasing it from 128 to 512 MB the server started creating indexes...
