Summary0015612: kernel BUG at lib/idr.c:1163!
every so often, usually every 3 to 6 days, one of our servers panics and reboots with the panic documented below.

It seem that there actually is an article from redhat about this issue here:, with the solution being "Upgrade to kernel-3.10.0-957.el7 from Errata RHSA-2018:3083 or later".

However upgrading to kernel-3.10.0-957 did not resolve the issue.

Please note that the error message from redhat differs with the one in my vmcore-dmesg.txt:
"Kernel BUG at lib/idr.c:1157!" vs. "kernel BUG at lib/idr.c:1163!"
I'm not sure if that matters.

It might relates with which I created a few days ago, occuring on the same servers aswell.

Any help / guidance is highly appreciated.
Steps To ReproduceProblem occurs randomly every 3 to 6 days.
