it looks like I'm stuck in memory allocation on java vm on linux server.
I use this command to check:
java -Xmx9g -Xms6g -d64 -server
server memory:
[root@….~]$ free -m
total used free shared buffers cached
Mem: 16017 1058 14958 1 41 758
-/+ buffers/cache: 259 15758
Swap: 1498 0 1498
Ulimit Settings:
core file size (blocks, -c) 1
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 128053
max locked memory (kbytes, -l) unlimited
max memory size (kbytes, -m) unlimited
open files (-n) 64000
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 128053
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
The Linux version is SUSE Linux Enterprise Server 11 (x86_64).
Java version:
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
I found out that it still works with -Xmx8330m, but no longer with -Xmx8331m. I do not know what is going on here, and why am I limited to this allocated allocated memory core?
Edit: Exact error message:
root@…..:/root> java -d64 -Xmx9g -server
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Thanks! Indie
