What type of system are you running this on, now? Anything of-note in
/etc/security/limits.conf (or similar) by chance? Any chance ulimit is being
set at the profile level? Anything interesting in ulimit -u by chance? (only
things off the top of my head at the moment - but, I should also be sleeping
about now)
Hope that somehow helps...

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
