I'm trying to start a new jvm with the command: java -version, but it report a error:
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 160088 bytes for AllocateHeap
# An error report file with more information is saved as:
# /users/xxx/xxx/hs_err_pid12365.log
Then I checked file /users/xxx/xxx/hs_err_pid12365.log, and I find out it say:
# Native memory allocation (malloc) failed to allocate 295856 bytes for Chunk::new
And the stack info also proves that the system can't allocate native memory:
V [libjvm.so+0xad3525] VMError::report_and_die()+0x2e5
V [libjvm.so+0x4e0457] report_vm_out_of_memory(char const*, int, unsigned long, VMErrorType, char const*)+0x67
V [libjvm.so+0xa9775f] universe_init()+0x35f
V [libjvm.so+0x631fd0] init_globals()+0x50
V [libjvm.so+0xa79b69] Threads::create_vm(JavaVMInitArgs*, bool*)+0x409
V [libjvm.so+0x6d7b4f] JNI_CreateJavaVM+0x4f
C [libjli.so+0x7ee4] JavaMain+0x84
C [libpthread.so.0+0x68ca] start_thread+0xba
But when I checked the available memory size using free -m. I find that the system still has enough available memory:
scada1:/users/xxx/xxx> free -m
total used free shared buffers cached
Mem: 7983 4867 3116 0 110 1031
-/+ buffers/cache: 3726 4257
Swap: 15257 71 15186
So why the system can't allocate memory when it has enough available memory
------- System Info ---------
The operating system info is:
scada1:/users/ems> uname -a
Linux scada1 2.6.32-5-linx-amd64 #1 SMP Mon May 18 04:02:09 UTC 2015 x86_64 GNU/Linux
The java version is:
jdk1.8.0_201
------- The hs_err_pidxxx.log Content ---------
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 160088 bytes for AllocateHeap
# Possible reasons:
# The system is out of physical RAM or swap space
# The process is running with CompressedOops enabled, and the Java Heap may be blocking the growth of the native heap
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=
# JVM is running with Unscaled Compressed Oops mode in which the Java heap is
# placed in the first 4GB address space. The Java Heap base address is the
# maximum limit for the native heap growth. Please use -XX:HeapBaseMinAddress
# to set the Java Heap base and to place the Java Heap above 4GB virtual address.
# This output file may be truncated or incomplete.

When allocating memory to a JVM, 10% to 25% of the memory is for the JVM process itself and the remainder is for the code running in the JVM. This means that a JVM that has been allocated 4 GB may only have 3.5 GB available to the code running in the JVM. This resource memory used by the JVM is often called overhead.
Easy way to solve OutOfMemoryError in java is to increase the maximum heap size by using JVM options -Xmx512M , this will immediately solve your OutOfMemoryError.
OutOfMemoryError is a runtime error in Java which occurs when the Java Virtual Machine (JVM) is unable to allocate an object due to insufficient space in the Java heap. The Java Garbage Collector (GC) cannot free up the space required for a new object, which causes a java. lang.
It seems you have overcommit disabled:
vm.overcommit_memory = 2
And the amount of currently allocated memory on the system has almost reached the limit. You can see it in /proc/meminfo section of the crash log:
CommitLimit: 15951192 kB
Committed_AS: 15837036 kB
The solution is to enable heuristic overcommit handling:
sudo sysctl vm.overcommit_memory=0
or to increase overcommit ratio:
sudo sysctl vm.overcommit_ratio=100
For more information see overcommit-accounting and man 5 proc.
