Мое приложение Java выходит из строя после того, как оно проработало пару дней во время JIT-компиляции. Может родная память дефрагментирована, а понадобилось всего 8Кб... У меня больше 700 потоков. 2Гб кучи (при сбое jvm использовался только 1Гб) Пожалуйста, помогите решить эту проблему.
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 8192 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.

# Out of Memory Error (os_solaris.cpp:2677), pid=25465, tid=47

# JRE version: Java(TM) SE Runtime Environment (8.0_31-b13) (build 1.8.0_31-b13)
