Submission from: (NULL) (131.204.85.131)
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
