bdb corruption when openldap is stressed
I am doing a bunch for stress test on an openldap server. the test basically involves hitting the openldap server using a multi threaded client apps that reads and writes constantly to openldap (read to write is 5:1). during the stress test the slapd core'd on me a couple times and left behind corrupted bdb files. i had to run db_recover to recover from the corruption. I tried this on openldap 2.1.22 and openldap 2.1.23 under redhat 9 running on a Dell box with a Pentium 4 cpu. i have the following questions:
1. how reliable is db_recover? given a choice between restoring the database from tape vs using db_recover which is more better?
2. has anyone else run into bdb corruption when openldap is stress tested?
3. anything i can do to reduce the chance for corruption?
