Hello Philip,
Yep you are right. restarting the audit daemon worked and it started giving error.
I will analyze the logs and do some more test cycles and then post all my finding here.

Hi Gupta,
Did you restart the audit daemon after clearing the logs? Just deleting the
logs might have resulted in auditd continuing to write to the log you'd
unlinked from its directory.
Hope that helps...

sorry for the typo:
[1] cleared all the /var/log/audit/* and ran the same command which give
memory error and no logs were generated i.e empty directory.

Hello William,
My current selinux settings are:

[2] install openjdk using "yum install java-1.7.0-openjdk-devel" and
ran the same command but using the openjdk java and it throw the same
memory error

Gupta,
You should share your selinux logs. They are under /var/log/audit
directory. Trigger the problem again and share the last couple of
hundred lines.
Before that though, find the directory openjdk installed and install sun
java there. Don't think using root home directory is a good idea and
selinux may be whining because of that. Or just install
in /usr/local/bin

Hello all,
Greeting and happy new year to all.
I am trying to sandbox a java application using selinux sandbox.
System details: Redhat 6 | x86_64 | no x server install | jdk7 from
oracle tar.gz version | cgred and cgconfig are stop
The cmd (run as root)
sandbox /root/jdk/bin/java -version
above cmd failed with
/root/jdk/bin/java: error while loading shared libraries:
libjli.so: cannot open shared object file: No such file or directory
Digging, revealed that "libjli.so" is RPATH shared library. so i thought
ok since sandbox is copying my bin/java to /tmp/sandbox_random therefore
a hardcode path will not be found.
Then i change the RPATH using "chrpath" utility and changed it to a
hardcode value
But still it showed the same error.
Then i used the -M -i option of sandbox and ran following command (i
included all the .so file it complaint about):
sandbox -M -i /root/jdk/lib/amd64/jli/libjli.so
-i /root/jdk/jre/lib/amd64/libjava.so -i /root/jdk/jre/lib/amd64/jvm.cfg
-i /root/jdk/jre/lib/amd64/server/libjvm.so -i
/root/jdk/jre/lib/amd64/libverify.so
-i /root/jdk/jre/lib/amd64/libzip.so /root/jdk/bin/java -version
Following command resulted in this error:
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory

Now i used the strace to see what happened and strace printed(small

I have enough space for sure
Can you guys please indicate what might be wrong ?
