Suggest slapd loglevel
Hello,
I have a crucial ldap server that is sick. It (slapd) dies about 5 times
a day. This is reoccuring on all 3 of our ldap servers (2 slaves), so I
am thinking it is a configuration issue on our main public server
(mail,www,ftp,ssh) or just a config error on the ldap servers.
I have the log level set at 256 and I am getting decent logs. I have
narrowed down the crash patterns. It seems that LDAP does not like 3 or 4
users. One in particular is a username, for this purpose lets say
danielk, is the last searched username before 90% of the crashes.
Here is an exert:

What log level can I run this at so I can get the reason why it crashes!!!
