I had the same problems, but I don´t use SPF or DNSRBL.
I used ./configure without arguments (I think --with-libbind is only
necessary if spf or dnsrbl, am I right?).

So - imho - there is only one "usual suspect" left, i.e. system limit
exhausted, although an ulimit -a shows an "unlimited" system.
Are there any other system restrictions to look at? Are there any
recommended sizes of RAM or virt.memory?

Deactivating mx-syncing made my systems more reliable.
