We have been running a virtual, multi domain mail server with the
Redhat 9, Postfix, Courier, openLDAP, Spamassassin, Razor, squirrelmail,
openLDAP is used for authentication.
Facing the following issues with openLDAP from time to time.
a) OpenLdap seems to get locked up every once in a while. i.e. While the
process is running, it fails to authenticate.
Because process is still running, our monitoring system, Monit, does not
recognize that as a failure.
Then we need to stop slapd. delete the /usr/var/openldap-data/__db.00*
files, restart ldap for it to start working again.
b) When the server load becomes high, 4 to 5 then authentication is
irratic. It works sometimes and sometimes it does not.
When server load became high to the tune of 16/18, ldap failed
What could be the reason for the above? anyone faced similar issues? I
wouldnt mind looking at commercial alternatives to openLDAP if the above
problems can be sorted out. ofcourse the best would be if the problem
lies with us and not the software as fixing it would be easier than
reinventing the ldap wheel.
Any and all help is always appreciated.
