После увеличения нагрузки (несколько проектов, часть из них - обмен
инфой с программой клиентом) сервер начал затыкаться
Это выглядит в браузере как
"Во время загрузки страницы соединение с сервером было сброшено."
При этом перестает отвечать фтп, ssh
такое ощущение, что ему не хватает то ли буферов, то ли еще чего. хотя
вроде всего достаточно
Подскажите плз, куда смотреть?
