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.

    In general, the statement says: if you have issues, and you run UEK, we are not going to rush with helping you. This is typically due to lack of testing under UEK. The question is why you need UEK, or better what is more important MongoDB support or UEK. – kofemann May 12 at 16:02
