I think these are separate issues. Regarding memory see the FAQ at
<http://wiki.list.org/x/94A9>. Regarding mail delivery see

>The TOP command shows   checkdbs memory usage at 32%/33%  always, 

checkdbs is run once daily by cron (default at 08:00). It should run
for a few minutes at most and then terminate. If you always have a
checkdbs running, something is wrong. How many lists in the
installation? What size lists?

Do you have a problem with stale locks? See the FAQ at

There is an issue with list caching in the qrunners that can cause the
qrunners to grow excessively large. See the post at
for more information and a patch.
