De repente erro = 'Não é possível alocar memória' (errno = 12) [fechado]

Então, nesta manhã, notei que meu site estava inoperante, entrei no meu servidor e vi que o servidor da web estava parado.

Quando tento iniciá-lo novamente, recebo este erro

 start -Dhttp.port=80 -Dapplication.secret=**********

O que me confunde é que ontem o servidor da web funcionou sem problemas e, de repente, esta manhã está inoperante? O Debian 7.8 está sendo executado no servidor.

Parece que de repente eu não tenho memória suficiente, certo? Eu realmente não sei o que fazer, para fazê-lo funcionar novamente, espero que alguém possa me ajudar.

Aqui está o arquivo completo do log de erros:

# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 715849728 bytes for committing reserved memory.
# Possible reasons:
#   The system is out of physical RAM or swap space
#   In 32 bit mode, the process size limit was hit
# Possible solutions:
#   Reduce memory load on the system
#   Increase physical memory or swap space
#   Check if swap backing store is full
#   Use 64 bit Java on a 64 bit OS
#   Decrease Java heap size (-Xmx/-Xms)
#   Decrease number of Java threads
#   Decrease Java thread stack sizes (-Xss)
#   Set larger code cache with -XX:ReservedCodeCacheSize=
# This output file may be truncated or incomplete.

vm_info: Java HotSpot(TM) 64-Bit Server VM (25.31-b07) for linux-amd64 JRE (1.8.0_31-b13), built on Dec 17 2014 20:40:15 by "java_re" with gcc 4.3.0 20080428 (Red Hat 4.3.0-8)

Seu log diz que, quando o aplicativo está travando, há 224852k de memória livre:

Memória: página de 4k, física 1027040k (224852k livre), troca 0k (0k livre)

Também vejo que você não possui uma partição de swap adicionada. É óbvio que seu sistema passa fome de memória. Então você precisa aumentar a memória física ou adicionar espaço de troca .

Para adicionar espaço de troca enquanto o sistema é executado, crie uma partição marcada como Swap do Linux. Que a partição identifique 82. Em seguida, use esse comando para configurar a partição como uma área de troca:

mkswap /dev/sda4

Onde /dev/sda4, é o arquivo do dispositivo.

Para ativar a partição, use:

swapon /dev/sda4

Depois disso, você deve ver SwapTotale SwapFreeentrar /proc/meminfo.

Para tornar isso permanente, adicione uma linha como esta em /etc/fstab:

/dev/sda4               swap                    swap    defaults        0 0
