Failed to start Name Service Cache Daemon

[Feelics]

Hi All,

I'm getting this recently on my server and can't quite figure out how to resolve it.

Service Check Raw Output (XID kqxkg8) The “nscd” service is down.

The subprocess “/usr/local/cpanel/scripts/restartsrv_nscd” reported error number 255 when it ended.
Startup Log Mar 14 18:26:46 server.fooweb.com nscd[31800]: /usr/sbin/nscd: relocation error: /usr/sbin/nscd: symbol __nss_database_lookup2, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference

Thank you,
Felix

Once CPanel is installed, it makes many changes. This becomes a cpanel, not a CentOS, question, so you are better off using their support channels.

Hmm...interesting...so you think this is cPanel causing the issue?

If so, unfortunately my hosting provider cannot update to CentOS 8+ and cannot update cPanel...

Do you know where I'd go to find support for cPanel?

Thank you in advance!

This looks like someone has either installed a version of nscd that is not part of CentOS 7 or they've updated the nss* packages with foreign ones. It's possible but not very likely that a recent nscd updates requires a newer version of the nss packages and did not require them so it installed alongside older packages that do not work.

What does `rpm -q glibc` say?

What other things want to be updated if you run `yum update`?

OK, so try the opposite direction, where does nscd come from?

rpm -qf /usr/sbin/nscd
yum list nscd --showdupli
