Are you using shm keys with BDB?
Not at this time.
I don't know anyone who is using BDB 5.3 at this point in time.
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. :)
