Problem with java

Hi, when I launch a java command, it gives me an memory allocation error.

[rootWEDOCOL01 ~]# cat /proc/version

Linux version 2.6.32-431.el6.x86_64 (mockbuild@x86-023.build.eng.bos.redhat.com) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) ) #1 SMP Sun Nov 10 22:19:54 EST 2013

[rootWEDOCOL01 /]# java -version

Java HotSpot 64-Bit Server VM warning: INFO: os::commit_memory(0x0000000758c00000, 176160768, 2097152, 0) failed; error='Cannot allocate memory' (errno=12)

Java HotSpot 64-Bit Server VM warning: INFO: os::commit_memory(0x000000060a400000, 350224384, 2097152, 0) failed; error='Cannot allocate memory' (errno=12)

java version "1.7.0_45"

Java SE Runtime Environment (build 1.7.0_45-b18)

Java HotSpot 64-Bit Server VM (build 24.45-b08, mixed mode)

however, if you launch the java command, specifying a low heap size, it does not give me error:

[rootWEDOCOL01 /]# java -Xmx102M -version

java version "1.7.0_45"

Java SE Runtime Environment (build 1.7.0_45-b18)

Java HotSpot 64-Bit Server VM (build 24.45-b08, mixed mode)

but, just get up even slightly, the error returns, even if in reduced form

[rootWEDOCOL01 /]# java -Xmx103M -version

Java HotSpot 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000f4600000, 23068672, 2097152, 0) failed; error='Cannot allocate memory' (errno=12)

java version "1.7.0_45"

Java SE Runtime Environment (build 1.7.0_45-b18)

Java HotSpot 64-Bit Server VM (build 24.45-b08, mixed mode)

could you help me?

Thanks!
