A question on GBUDB utilization. I show a current utilization of 95% (from the log file) which I assume means the amount of memory used from what is set aside for gbudb entries. Is that correct? What happens when more entries are added? Does the GBUdb grow or does it get pruned out? Will gbudb XCI commands (like <bad>) show up in a log file?
