slapd Memory Usage
Title: Message
Hi,
I have a concern
regarding slapd memory usage.
I have isolated
version 2.1.22 with only the NULL backend compiled in.
We are placing the
slapd server under load and monitoring it's memory usage using
pmap.
We are noticing that
there is alot of "anon" memory being allocated, and I'm wondering what is
allocating this?
Is this a memory
leak?????
I am running slapd
on Solaris 8.
As of now, we've
seen an increase in total memory of over 200k in about 1/2 hour of running under
load.
I have everything as
default, meaning I have no special entries in the
slapd.conf.
Any help would be
appreciated.
