[rds-devel] RDS-tools issues

Hi, Santosh,


I can not work with latest tool, either.


Here is the test log:

Is there anything wrong with my test parameter or rds driver?

This was very old issue and has to to do with older tools and kernel. Another user reported this a while back [1] Latest tools: https://oss.oracle.com/git/?p=rds-tools.git;a=summary Kernel: Linus's kernel.
