Re: SLAPD denial of connections under load

I suggest you separate the mail server from the LDAP server. The high
load on the system from the mail delivery agent may be preventing slapd
There isn't enough information here to determine a course of action. You
need to get more info before making suggestions on how to fix the problem.
My guess is that slapd is out of file descriptors or there are too many
outstanding connections. Using a program like lsof may help to determine
if that's the case. There is no way that any mail server can generate
more queries than slapd can handle when both are running on the same CPU.
I wasn't concerned about the mail server generating more queries than slapd
could answer, I was more concerned about the mail server consuming enough
resources that affected slapd's ability to respond. I would put running
out of file descriptors, etc, into that category. ;) I suppose separation
of services is a philosophy more than anything, but it is one I tend to
apply in an infrastructure environment.
