Red Hat 7 Kernel Update Breaks NNMi 10.40

Jump to solution

Greetings everyone,

Been having an issue with Kernel Updates for Red Hat 7.  Been running nnmi10.40 on RH7 for months with no issues the working kernel was 3.10.0-693.5.2.e17.x86_64  this morning we updated the server which included new kernel 3.10.0-693.17.1.e17.x86_64  and now the processes will not start.

if we do a clean install on this new kernel everything works file but for some reason we have been unable to yum update the kernel on an existing system.

Found this post From Dave Young related to OVJBOSS  and we gave it a try,  when we modified the nms-local.properties file and added the new jdk that was updated yesterday it then worked.

Hello David

Thanks for posting

Can you please open a support case with us? We will need to troubleshoot this issue,  it can be related to a security problem that is affecting NNM services. Probably this can be associated with the problem we had in the past with 10.20 and an specific kernel version.

But we will need to confirm and verify this behavior.

Regards,

Vincent Montenegro Mena

Vincent,

We actually isolated this to Red Hat 7 JAVA patches not the kernel.  We upgraded the Kernel independently and everything ran fine.  Once the JAVA updates were applied from the YUM repository that is when the processes would not start.  I am going to provide the exact JAVA patches that were applied that we believe break the application.
