Не могу понять - в чем дело - куда девается свободная память?
На машине с 8Гб RAM, с одной запущенной VPS, все лимиты на память которой были выставлены 768M и практически полным отсутствием процессов, занимающих память на HN, свободно лишь только около 850M.
Прошу заранее прощения, если решение очевидно, или уже освещалось
в данном форуме.
Вот некоторая информация о системе:
