[Important] Limit on the number of users in a group?
when a group in /etc/group contains over 100 members, chgrp stops
functioning properly when a _numeric_ group ID is passed as an argument. Note
that this is a different situation then the 32 group limit that linux
specifies in which a user may not be a part of more than 32 groups. This is
when a group contains more than 100 or so users.
Providing a group name as an argument works correctly in all cases.
However, when the 100+ member group exists in /etc/group, providing a numeric
group ID as an argument sends chgrp into an infinite loop eating up all
available resources -- happens to render the 2.4.x OOM killer useless as
I have recently upgraded from stable to testing, but I've only noticed
this bug recently, and I am unsure if it has been there before.

RedHat has addressed a similar bug in April
They have fixed the bug in the RHSA-2003:089-11
advisory (see http://rhn.redhat.com/errata/RHSA-2003-089.html).
Is this a known bug in Debian? Please, reply all to
It is very important because this is a production machine (for lack of a
better name) and provides real services to our users. Having the machine die
because a script running from cron hits this bug is not nice on the weekends
when no access to the machine can be obtained.
