Since you mention sssd, and it is apparently loaded by bash, are the
users and groups list from a remote server (such as LDAP)?

That could cause bash (or whatever program which tries to determine the
name of a user/group) to freeze if its cache expired and it needs to
refetch those  from a remote server (e.g. it may be downloading the list
of all the users in the company).
