Not at this time.
I don't know anyone who is using BDB 5.3 at this point in time. I
would back down to something less recent and see if you see the same
issue. I've used BDB 4.7 for quite some time w/o issue.
Well, with 4.8.30, the problem is still evident. Overall, using
delta-syncrepl seems to make a large difference. With my previous test
(still with bdb 5.3) and delta-syncrepl, the slapd process grew to 16G
before dying. With delta off (removing the 'syncdata=accesslog
logfilter="(&(objectClass=auditWriteObject)(reqResult=0))"' portion of
the olcSyncrepl line) the node started and finished loading the entire
DB and grew to about 5.7G in total.
I don't have the bdb 4.7 tarball handy... but I'll being giving mdb a
shot next and see if it behaves the same.
Also, your BDB cachesize seems undersized, given the size of your DB.
It should be no less than dn2id.bdb + id2entry.bdb + 10% for growth.
Personally, I prefer to keep my BDB cachesize at <size of DB>, or in
your case, I'd set it to 2 GB, i.e.:
Thanks, if I stick with hdb I'll make that tweak. Those values are
pretty old, I've been shy about changing too much while changing
everything else. :)
