Hi,

I'm having some trouble when starting a openLDAP 2.4.35.

In the log files I have the message:
** ld 0x7f11e4100910 Outstanding Requests:

   outstanding referrals 0, parent count 0
  ld 0x7f11e4100910 request count 1 (abandoned 0)

Aborted

I already try to delete de lock.mdb and data.mdb files in order to recreate then (in case of a db corruption), but the error continues to pop...

I also saw the thread "(ITS#7756) LMDB assertion failed in mdb_page_search_root (http://www.openldap.org/lists/openldap-bugs/201311/msg00054.html).

Is there anyway to bypass this error ?

Thanks in advance for your help,
Marc
