SIGFPE received, aborting Aerospike

I tried to deploy the community edition of aerospike on kubernetes using the helm chart. I am seeing following error. Can someone point me to the possible reason?

This error is only happening on pod-0 of statefulsets. Other 2 pods are in running state but looks like waiting to connect to pod-0 which is dead.

This would indicates that this code:

static uint32_t
select_sid(void)
{
	static uint32_t rr = 0;

	return rr++ % g_config.n_service_threads;
}

triggered an illegal arithmetic operation (SIGFPE).

I take this to mean that the n_service_threads configuration was somehow zero. But I haven’t been able to find a way for that to be true.

I have few modification to helm chart: 1- cluster domain 2- use my own storage class for PV

Let me know if that might help to narrow down.

Is there a stable version of chart/images which might work?

As far as I can tell, this shouldn’t happen, the code prohibits that configuration from ever being zero.

Is this issue reproducible?

Is the RAM on the node ECC?

Hi Kevin,

Gmail filtered this messages so couldnt see till now. and these messages were not showing up on the discussion thread. I am not falimir with "hardware logging context. Do you want to me to put that json block as it is in the conf file? or add some hardware detail there?

Thanks, -Arvind

Sorry for the confusion, I removed those comments because they were a dead end. If the server had found zero cpus it would have crashed well before the point where this crash occurred.

But I am interested in these questions:

yes issue is reproducible everytime. Regarding RAM I am not sure but I am assuming they are ECC, these are Intel 1U servers.

  • Could you share your /etc/aerospike/aerospike.conf?
  • Are you configuring auto-pin adq?

I am using the mostly default settings from helm chart (except storage configuration and kubernetes cluster domain)

Ok, doesn’t look like you are using ADQ, so the stack trace I printed doesn’t make sense. In the same container, could you run:

addr2line -fie /usr/bin/asd 0x169c33 0xb9554 0x7fbbfc1a00e0 0xc8250 0xc85a3 0x157060 0x7fbbfc1964a4 0x7fbbfb015d0f

Hi @kporter, for some reason when I deployed it again last night now aerospike cluster is working. I don’t see any error. Which is good but same time very odd as I have not changed/fixed anything to make it work. Not sure if its helpful now but below is the output of cmd you asked for:
