возникла проблема, странно повисает ацель, accel-cmd show stat, accel-cmd show sessions и т.д. просто повисают ничего не показывая
при этом новые сессии не поднимаются, а те которые уже были вроде как нормально работают, при этом ацель перестаёт писать логи
в системном логе при этом наблюдается такое

кстати места на дисках тоже полно и ротация логов настроена
читал про ошибку INFO: task ХХХ blocked for more than 120 seconds. и по рекомендациям сделал
vm.dirty_background_ratio = 5
vm.dirty_ratio = 10
но к сожалению не помогло
