[SOLVED] Cron has stopped working

Anytime there is a scheduled cron task, journal shows this sort of ouput:

Aug 14 03:00:01 ryzen crond[14052]: PAM unable to dlopen(/usr/lib/security/pam_unix.so): /usr/lib/libpthread.so.0: symbol __write_nocancel version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference

I tried a full system update. 

Also tried a reboot. 

No help.

Not sure if this is relevant:

# orrin @ ryzen in /usr/lib [5:08:04] 
$ ls -la | grep libpthread
-rwxr-xr-x   1 root root    155296 Aug  1 13:30 libpthread-2.28.so
-rw-r--r--   1 root root    456886 Aug  1 13:30 libpthread.a
lrwxrwxrwx   1 root root        15 Aug  1 13:30 libpthread.so -> libpthread.so.0
lrwxrwxrwx   1 root root        18 Aug  1 13:30 libpthread.so.0 -> libpthread-2.28.so

Tried some searching but didn't finding any recent similar issues.  Any thoughts?

Re: [SOLVED] Cron has stopped working

Yes thanks.  Simply restarting cronie service did the trick.
