In case it's helpful:

# ls -l /usr/lib/security/pam_unix.so
52 -rwxr-xr-x 1 root root 51984 Jun 16 2014 /usr/lib/security/pam_unix.so*

Also - the errors and SEGV started after the glibc update - and have repeated on the hour, the half hour and at 1 minute past the hour.

The cron events are not processed - one key event is the nightly backups ... unfortunately.

You must restart crond (and anything else which uses dlopen on glibc libs) after a major glibc release. Nothing new here.

Yah duh on me - I thought I rebooted after the update but in fact it came in after. Will reboot and confirm all is well and close.

thanks
