При сборке ядра значение maxusers=0 (сейчас maxusers=384), но не думаю, что причина имеено в нем.
Дело в том, что на соседней машине с 5.5 и такой же конфигурацией (за исключением того, что машина I386, а не amd64+SMP как в случае с 6.1) и тех же манипуляциях, все нормально.

Вот не меняется оно и все, хоть кол на голове чиши!
К сожалению, под рукой нет второй платформы amd64, что бы провести следственный эксперимент ;)
