could you enable logging of internal operations. I have the suspicion that one of the plugins does some extensive searches and they are done in the txn of the modrdn operation Thanks Teko, sorry I had missed c2. so this shows two things: - memberof does a search of all backends, not sure if this is necessary or can be prvented by config (Thierry?) - it does substring searches for member, uniquemember, owner, seealso, memberuid - and I don't think they all have substring indexes. Is it necessary to include owner and seealso in the member attrs ? indeed config parameter memberOfAllBackends is likely turned 'on' (default is 'off') that explain all backend lookup. Is it necessary, it depends on how data are spread on backends. Also in such case substring index must be tuned on all backends. In case they are not indexed it leads to an unindexed search under a txn ! The change will be provided in bz1812286. Closing this as duplicate. *** This bug has been marked as a duplicate of bug 1812286 *** |
