slapd ran great while testing (no crashes). once in production it dies
randomly but fairly often.  I have several backtraces and I am collecting
debug output now.  Our database has approx 30,000 entries.

slapd.conf lines:
database        ldbm
index           cn eq,sub,pres,approx
index           sn eq,sub,approx
suffix          "o=Auburn University, c=US"
dbcachesize     10000000
cachesize       50000
