Problem: bdb(dc=uvm,dc=edu): PANIC: fatal region error detected; run
Somehow a bdb log file got created and owned by root. Based on the
timestamp and the contents of the log, it appears that it happened
because the nightly slapcat (which runs as root) did a checkpoint.
Either that or it was absolute coincidence that the checkpoint was run
at the exact same time (00:17:09) as the slapcat. Slapd runs as user
ldap, so I don't know how slapd would have created the log file owned
Should slapcat be doing checkpoints? Is this a known problem? Do I
need to change the way the ldap user is defined on the Red Hat system
so the slapcat can run as user ldap?
slapcat invokes the usual backend open and close routines, and the
back-bdb close routine always does a checkpoint before closing its
environment handle. Perhaps it should skip this call when accessing the
database in read-only mode.
