Indigo for 2.12.2 running on 64 bit Linux

I've installed Indigo 1.1.4.X from the Stable community contributions site into KNIME running on 64 bit Linux (red hat enterprise server).  This version of the KNIME analystics platform was installed as part of the installation of the KNIME 4.1.2 server.  I can run KNIME fine and was able to successfully complete the installation of Indigo integration extension, however when I run KNIME after restarting it I get the following errors in the log and the node extension is not shown in the node library:

I tried installing the 2.12.2 64 bit client on my Windows 7 system and installed the Indigo 1.1.4 extension there from the same Stable community platform site and it seems to work fine.  Has anyone successfully used Indigo with 2.12.2 on Linux?   As I said, the analytics platform that was installed is used for the KNIME server and it is installed via a special "install-rmi" script so it may be that this version of the analytics platform is a bit different.

Any help would be greatly appreciated.

 

After looking at the knime.log file it turns out that there where errors relating to this problem.

Giving write permissions to the group Others, for the directory /tmp/jna fixed the problem. Thanks for your help with the debugging.
