java.lang.NullPointerException

Hi

When CAS starts, it gets to a point and then starts throwing loads of 'java.lang.NullPointerException' errors in the CAS log and the CPU spikes to 100%. Restarting the host resolves this, but the issue appears again a few days, sometimes up to a week later.

Any idea what could cause this and how to resolve it? I'm running DCRUM 12.3.3 at the moment.

I'll log a support ticket for this too and update here if I have feedback.

Andre,

We must see the log, would you please attach one?

Hi Adam, I've attached the logs.

I'll check today or tomorrow if the problem persists, in which case I'll open a support ticket.

What I noticed in the meantime is that it seems as if the host loses network connectivity and the only way to resolve that, is to restart the host. We're investigating what the cause could be, but it is not related to our product.

Andre,

It looks like the Farm does not like network problems, but we cannot say anything more w/o more logs.

Please open support ticket with full ExportConfig.zip as it would require Dev analysis.
