Surely one can code round that little problem. Instead of maintaining a history table which records the number of times the last message has been received, one records the number of times in the last N seconds that a given client's last message has been repeated. The history table, instead of being one count, and one string buffer, becomes an array indexed by clients of with each item containing a count and a buffer and a timestamp. Obviously the table would have to be size limited and probably idle-time-purged, to avoid it eating up resource. Ted

One problem with this feature is that it can only work if the last 137 syslog events to occur were the same event. We run a large centralized syslog server environment, with lots of syslog clients, and as such this sort of limiting feature never really gets to work, as it's quite rare for one event to occur record after record without some other client squirting in a new record.
Oh well...
