My RHES7.6 server reboots itself once every two days!
The current version is
Linux version 3.10.0-957.21.3.el7.x86_64 (email@example.com) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC) ) #1 SMP Fri Jun 14 02:54:29 EDT 2019
This is going on for sometime (nearly a year) And vmcore shows the following:
crash /usr/lib/debug/lib/modules/3.10.0-957.21.3.el7.x86_64/vmlinux /var/crash/127.0.0.1-2019-07-09-12:53:42/vmcore

There don't seem to be any solution I can find. I have upgraded and downgraded kernels but no luck.
In contrast I have an old rhes 5.6.4 that is running for 10 years rock solid on an old hardware. No problem of this sort.
I trust someone in the community can help me?
