Making a little more progress on this, slowly. I'd forgotten that I have a regexp table that's rather large, containing 1626 expressions. I added it to proxymap, and this action dropped the size of my smtpd processes dramatically, by about a factor of 5. Apparently, even though this regexp table has only 1626 lines, it requires far more memory than my big 'countries' cidr table which has 11148 lines. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 14411 postfix 20 0 20276 16m 1480 S 8 4.3 0:00.51 proxymap 14410 postfix 20 0 6704 3368 2208 S 0 0.9 0:00.04 smtpd This is making good progress. Seeing the smtpd's memory footprint drop so dramatically is fantastic. However, I'm still curious as to why proxymap doesn't appear to be honoring $max_idle or $max_use. Maybe my understanding of $max_use is not correct? It's currently set to 100, the default. Watching top while sending a test message through, I see proxymap launch but then exit within 5 seconds, while smtpd honors max_idle. Is there some other setting I need to change to keep proxymap around longer? -- Stan
