I haven't compared the same build with and with out the fixes for ITS#7961,#7987, however I can confirm that under the same environment, RE24 (scheduled for 2.4.41) remains stable while 2.4.40 crashes from time to time. Actually I would strongly suggest upgrading to 2.4.41 when available.

Thanks for the confirmation, we'll resolve this ITS.

    I am in the process of doing so. Do you have in mind a specific
    commit/fix in REL_EN that might have solved this; That would help me
    reproduce the initial problem (in 2.4.40) and confirm the fix
    (in REL_ENG).


Most likely 9a72292ac134f80c1befe8102dee11__60e57a92ec


    For start I will try to upgrade to REL_ENG the same system from
    which I
    got the debug log, to see if that would help recover (although I
    have no
    great hopes).

             slapd with an mdb backend, after some time of normal
    operation,
             may reach into a
             situation where you can almost predictably crash it, with a
             simple modify
             operation.


         Please test RE24 and see if you can still reproduce this issue.
