Cause

Sometimes the Sametime awareness status of a user is visible as a question mark in your contact list.

Apart from the question mark icon, you might also see the warning message stating the the number of your contacts from the server community exceeds the number that can be monitored for availability. as shown in the 2nd picture.
How does it arise and how can it be controlled or configured.




Answer

The status that is shown in with the question mark sign is "unknown". This could be triggered when the watch limit on the server side is exceeded. The watch limit is something that defines max number of people that can be watched by the name resolver.

For example, if a server has it set as something like 500, when the threshold is reached, the status of the extra livenames are not monitored and the "unknown" status may return when a look up is requested (like in the card).
It is controlled by the following parameter in plugin_customization.ini:
com.ibm.collaboration.realtime.people/watchLimit=<integer>
After you see when the "unknown" status shows up, and that if the user deletes some contacts from his contact list, the unknown status should change to real status.

And for the warning message see the following parameter in plugin_customization.ini:
com.ibm.collaboration.realtime.imhub/warnWhenWatchLimitExceeded=boolean

It is used so that when the watch limit is in effect, specifies whether or not to warn user when the number of contacts that can be monitored is exceeded.

On server side threshold is defined in sametime.ini by the following parameter:
MAX_NUMBER_OF_SUBSCRIBES_PER_CLIENT

It is used by clients in order to enforce the limit on the client side. When a user exceeds this threshold, and add the threshold+1 subscription to his watch list, the Buddylist detects it, and notify the client that
he won't get awareness on the new name that was added to the watch list before decreasing the total number of subscriptions.
