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.
