The following options seem to have a direct impact on how fast I run out 
of resources (obviously) . The more I increase them, the faster I get 
the mmap error.

*mupdate_workers_start
mupdate_workers_minspare
 mupdate_workers_maxspare
mupdate_workers_max

I have them all set to the default values right now.

Right now my ulimit is configured like this:

core file size        (blocks, -c) 0
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
max locked memory     (kbytes, -l) unlimited
max memory size       (kbytes, -m) unlimited
open files                    (-n) 200000
pipe size          (512 bytes, -p) 8
stack size            (kbytes, -s) unlimited
cpu time             (seconds, -t) unlimited
max user processes            (-u) unlimited
virtual memory        (kbytes, -v) unlimited

and Im still getting the mmap error. Got it once this night... so far 
cyrus didnt throw any DBERRORs though
