Why is Splunk crashing every 5 seconds on a single host with error "WARN Thread - HTTPDispatch: about to throw a ThreadException: pthread_create: Resource temporarily unavailable"?

Explorer

So, I pushed Splunk out to our entire non-production AIX farm. It is working on 50 hosts just fine, but, fails on a single host.

From splunkd.log, the only help I found was

11-01-2016 15:45:04.925 -0500 WARN  Thread - HTTPDispatch: about to throw a ThreadException: pthread_create: Resource temporarily unavailable; 35 threads active

I see this line too, but, I assume it is because the forward has not checked in with the deployment server yet..

11-01-2016 15:44:52.210 -0500 ERROR TcpOutputProc - LightWeightForwarder/UniversalForwarder not configured. Please configure outputs.conf.

Here is a crash dump.

Re: Why is Splunk crashing every 5 seconds on a single host with error "WARN Thread - HTTPDispatch: about to throw a ThreadException: pthread_create: Resource temporarily unavailable"?

Ultra Champion

I assume we are talking about the forwarders ...

A similar case at - Splunk Forwarder Crashes - pthread_create: Resource temporarily unavailable

@dwaddle speaks there about the number of threads but in your case we see - Threads running: 34.
Can you please post the output of ulimit -a? as quite often the servers don't have the proper ulimit configurations.

A good discussion about forwarders' crashes on AIX at Why does Splunk 6.1.2 forwarder on an AIX 7.1 machine keep crashing?

Can you please post the output of ulimit -a?

Looks great!!! I would open a ticket with Support especially since you have the crash dump.

Hi Ericmck2000,

What was the reason for the error that you faced? Because we are facing same error with UF.

Thank you,
Kranthi
