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.
The fact that switching off delta changes the behavior would point pretty
squarely at a bug in the delta-sync consumer code, not anything in the
underlying backend. If you can produce a small test case to demonstrate the
problem, it would be a good idea to post this to the ITS.
