Используется большая память, буфер свободен, приложения не запущены

Много раз искали, прежде чем спросить о моей проблеме. У меня 6 ГБ ОЗУ, 4 в настоящее время используются, 2 свободно, количество буферов мало

# free -m
             total       used       free     shared    buffers     cached
Mem:          5982       4031       1951          0          2         16

Swap:  
   1023          3       1020

Но мой пс говорит, что этот барана не обрабатывается ...

Понятия не имею, какой процесс потребляет этого барана. Перезагрузка сервера решает проблему на несколько часов в день.

Я уже тестировал:

Буфер для очистки: sync; echo 3 > /proc/sys/vm/drop_caches
Остановить как можно больше процесса

memory buffer

Вы работаете на виртуальной машине VMware, и для виртуальной машины включено расширение памяти. Таким образом, гипервизор может динамически «забирать» память у вашей виртуальной машины и разрешать другим виртуальным машинам использовать ее (поскольку ваша виртуальная машина ее не использует). В VMware это проявляется как необъяснимая «использованная» память.
