segfault in libc-2.28.so - yum update after clean install

Post by tomtom902 » 2020/06/28 22:20:16

On a running a "yum -y update " after a clean install of CentOS 8.2.2004 (minimal, with software RAID), this system throws a segfault. Issue is not seen on CentOS 7 (CentOS-7-x86_64-DVD-1810).

[ 150.749517] ld[13854]: segfault at ffffffffffffffff ip 00007f7bfead2c79 sp 00007fff834cc118 error 5 in libc-2.28.so[7f7bfe975000+1b9000]

Issue is also seen on 1 other system (same specs).

CPU: Intel(R) Xeon(R) Silver 4216 CPU @ 2.10GHz
Memory: M393A4K40CB2-CTD * 4 (also tried with 1)

[root@cph2 ~]# uname -a
Linux cph2 4.18.0-193.6.3.el8_2.x86_64 #1 SMP Wed Jun 10 11:09:32 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Any ideas on what we could do here?

When you say the system throws a segfault, do you mean WHILE it's running yum?

Turned out to be hardware related, we replaced the CPU + motherboard with the server vendor and the segfaults are gone now.
