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).
