Process 30567 increased its virtual memory size from the first report to the 
second, but not from the second report to the third. Did its virtual memory 
size continue to increase?

Does only one ldmd(1) process increase its virtual memory size? If so, what 
does that process receive (you can find that information in the LDM log file -- 
search for the PID and the word "Starting".

Is there anything untoward in the LDM log file from the process in question?

Regards,
Steve Emmerson
