This is a relatively high-volume environment, with 4 servers running
with mirrormode to enable multi-master replication. The current
database size is about 900mb. Is there any setting that could limit
this memory usage? I don't feel this is "normal" considering our DB
size and cache sizes.
Very likely ITS#6660, you need to update to 2.4.24.
Also make sure you use an alternative memory allocator if you are
running on Linux, such as tcmalloc from the google perf tools package,
Can you expound a bit more on that, Quanah, or point me at some more
complete information on why using a non-default memory allocator is
beneficial for OpenLDAP on Linux?
I've been subscribed to the OpenLDAP devel and now technical mailing list
for quite a while and I don't recall seeing anything stated in such strong
terms about not using the default malloc/free on Linux.
It's been discussed in detail several times, but not for a few years.
