@summersmd

What did you increase your max open files to? Have you configured systemctl? There is a bug in Linux that when ulimit change does not take effect if service is configured via systemctl

Bug: [https://bugzilla.redhat.com/show\_bug.cgi?id=1364332](https://bugzilla.redhat.com/show_bug.cgi?id=1364332)

Thanks
