CSS Sub Module LifeTick Failure

Had an issue last night where CSS11503s failed-over. Within the tech-support the reason why is detailed below.

MAY 16 22:25:31 1/1 486 SYSSOFT-0: ONDM: Rebooting system: Sub Module LifeTick Failure.

So does this error indicate the Controller Card has lost sight of either the SSL or 16Port FE module and rebooted. Is this an identified/known bug when running sg0750004 ( on a 15503?

Dump mode is enabled. Should the CSS then dump to a core file for additional diagnostics? as <No files available>

Thanks in advance

Re: CSS Sub Module LifeTick Failure

Do you have app-udp configured or an ISC link ?

The only 2 lifetick related bug are related to either of of these.

I would strongly suggest an upgrade to the latest 7.50 code. You are currently running to very first version of 7.50.

Is this not more likely to be a SSL hardware module related issue? The CSS11503 has crashed and reloaded twice in 24hours.

Re: CSS Sub Module LifeTick Failure

here are the 2 ddts related to lifetick failure that are well-known in your version



The first one is due to the ISC link being configured and will result in lifetick failure.

The 2nd one is a buffer leak in the CAPP-UDP code resulting as well in lifetick failure.

This could also be a hardware issue, but the lifetick being sent by the SCM and all other modules responding to it, the problem could be any module or the chassis.

Or one of the know bugs.

So, you can either upgrade know to the latest 7.50 image and hope this is a known issue, or open a TAC case and provide a core dump that the box probably generated.

With the core we can verify if this is a known bug or hardware related.

With just the error message there is no way to tell what is causing the problem.
