Hi,
I'm running a munin plugin monitoring memory usage (multimemory) for
various processes, and don't see the DSPAM main process growing in
memory over time. I do see a nightly spike when dspam_maintenance kicks
off, but after it is finished, memory usage returns back to normal.
I have to note that this is a small setup, processing about 150
mails/day. DSPAM git running as daemon, postgresql backend. Attached is
a monthy graph.
