On an architecture with 2 servers replicated using delta-syncrepl (MMR), doing some modififications on one server might lead to a core dump, where the stack trace shows that the mod->sm_numvals value is not what is expcted in the modify_add_values value :

... if ( !BER_BVISNULL( &mod->sm_values[mod->sm_numvals] )) { unsigned i; for ( i = 0; !BER_BVISNULL( &mod->sm_values[i] ); i++ ); assert( mod->sm_numvals == i ); } ...

Here, the assert fails. Here is the stacktrace :
