Before we suspect glibc, it's better to clear what actually causes
your problem. 2.3.2.ds1-20 and -21 do not have any nscd/NSS
modifications. The almost all code have been used over 1.5 years. So
I think it's your local environment/machine trouble rathar than glibc
issue.
You wrote you upgraded to the -20, but it's not the latest version.
Which version did you use without problem? Which version do you have
problem with? What packages did you upgrade with glibc at that time?
Please describe in detail.
