Got that right :) Seriously, I think I misread the doc for
configure... I thought the default was nmladm rather than nmlvadm.
if I use nmladm, would the admin get a notification? Call me
paranoid, but I usually run with "full" functionality until I
know everything is working.

Well, now I'm really in uncharted territory. I have the output
from strace... and I either don't know what I'm looking at, or
I've found the problem. Everything seems to be ok, and then
there's this:
25934 read(3, "n;\n $desc =~ s/\\n\\t/ /g;\n $now"..., 4096) = 4096
25934 read(3, "ondition(\"cannot open $qmailinje"..., 4096) = 4096
25934 brk(0) = 0x8301000
25934 brk(0x8322000) = 0x8322000
25934 brk(0) = 0x8322000
25934 brk(0) = 0x8322000
25934 brk(0x8321000) = 0x8321000
25934 brk(0) = 0x8321000
25934 read(3, " if (¬ify_addr(\'precips\')) {"..., 4096) = 4096
25934 read(3, " $destring=\'problem\';\n $qu"..., 4096) = 4096
25934 brk(0) = 0x8321000
25934 brk(0x8342000) = 0x8321000
25934 mmap2(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = -1 ENOMEM (Cannot allocate memory)
25934 mmap2(NULL, 2097152, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_NORESERVE,
-1, 0) = -1 ENOMEM (Cannot allocate memory)
25934 mmap2(NULL, 1048576, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_NORESERVE,
-1, 0) = -1 ENOMEM (Cannot allocate memory)
25934 mmap2(NULL, 2097152, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_NORESERVE,
-1, 0) = -1 ENOMEM (Cannot allocate memory)
25934 mmap2(NULL, 1048576, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_NORESERVE,
-1, 0) = -1 ENOMEM (Cannot allocate memory)
25934 brk(0) = 0x8321000
25934 brk(0x8342000) = 0x8321000
If I'm reading this correctly, the mmap2 call is returning a
memory allocation error, right?
I remember reading in the install doc that memory would be an
issue. It said to keep testing until there were no more memory
errors in the qmail log... then add another 1.5Mb. My memory
errors went away with softlimit -m 6000000... so I upped it to
7500000.
top says I'm using a lot of memory, but I have a ton of swap left.
Assuming this is what's causing my problem, does swap not do me
any good here?
