JVM crashes with error=‘Cannot allocate memory‘ (errno=12)

error='Cannot allocate memory' (errno=12)

jvm崩溃， 无法分配内存。

JVM正在尝试分配127926272字节的内存，而空闲物理内存不足，并且交换时没有任何可用内存。

产生一个hs_error.log文件

OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000e9c80000, 127926272, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 127926272 bytes for committing reserved memory.
# An error report file with more information is saved as:
