IBM Worklight 6.2. Analytics installation on Linux 64 bits. Issue with lib libsigar-amd64-linux.so

Question

I' trying to install analytics in a WAS 8.5 standalone server in a Linux redhat 6 64 bits.

uname -a
Linux localhost.localdomain 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

After installing the .war in the server and configuring the classloader with parent last, when I try to access to the console I get this exception in the log although the console is displayed.

[8/6/14 12:31:16:501 EDT] 00000051 SystemOut     O 0 [WebContainer : 1] DEBUG Sigar  - libsigar-amd64-linux.so (Not found in java.library.path)

I have not found any documentation about this in the Knowledge center or even in google. We have tried with yum but we haven't found the lib.

Any hint?

This is a defect. The workaround is to open the analytics WAR file and delete the following directory:

WEB-INF/lib/sigar

The analytics console isn't using sigar, so there shouldn't be any issues when deleting this folder.
