Symptom
The following message can appear in the console or system.log:
<time> {host} lookupd[pid]: truncating list at "{host}" (maximum 1024 of {#} values) <time> {host} last message repeated # times
Key:
1. <time> is the time that the message was logged in the console and system.log. {host} is the name of the computer on which the issue occurred or the user record that was passed to lookupd that initiated the query.
2. pid is the process ID of lookupd, the process that caused the message.
3. {#} is the total number of users in the group that lookupd is accessing.
4. # is the number of times the message is repeated as lookupd accesses the group.
Solution
This message is harmless. It does not reflect an actual limitation in the number of users that may be the member of a group in Mac OS X Server or Mac OS X.
These messages can occur on Mac OS X Server computers that have over 1024 local users as members of a single group. It can also occur when the Mac OS X computer has Directory Services set up to bind to a directory that contains more than 1024 users. You can safely ignore these messages.
