..if popper service is stopped the queue are emptied in a few minutes.
I have read the documentation about 'Perfomance' but I haven't
solution for my problem, What can I do to solve my problem ?
Thanks in advance.
When you say you are experiencing "queue increase" you mean that
incoming mail builds up and is not delivered?
Is your system CPU-limited, memory-limited, or I/O-limited? That is,
if you use any kind of performance monitor, even just 'top', do you
see high load average and no idle CPU? Or, are you seeing excessive
pageouts?
Also, have you tried enabling server mode? As long as your users
don't access their mail using any sort of local program, it should be
OK. You can try also setting fast-update. See the "Performance" and
"Server Mode" text in the GUIDE.pdf file.
