Re: зависания на read (debug)

Стандартная схема
nginx - apache 1.3.33
Имеем кучу apache в reading состоянии. Судя по логам и трейсу, nginx
делает коннект, апач его accept и вистит в read состоянии. Однако nginx
не спешит ему говорить что-то... и или говорит через большую паузу или
отваливается по таймауту (upstream timed out (110: Connection timed out)
while connecting to upstream).
Предположительно проблемы начались после переезда на 2.4.33.3.
Подскажите, что крутить или какую доп инфу дать.
Попробовал поставить обработку через select - пока все работает.
Debug выглядит так...
