I am running
MongoDB v3.4.9 on Oracle Linux Server release 7.7 with the Unbreakable Enterprise Kernel (UEK) 4.14.35-1902.3.2.el7uek.x86_64 for testing purpose.
UEK is not official supported on Oracle Linux based on MongoDB doc:
MongoDB only supports Oracle Linux running the Red Hat Compatible Kernel (RHCK). MongoDB does not support the Unbreakable Enterprise Kernel (UEK).
The basic capabilities of MongoDB are currently running, but I wanted to know, what could be the potential problems, if I wouldn't migrate the kernel from UEK to Red Hat Compatible Kernel (RHCK). I couldn't find any information about it.
