the following valsort + dynlist combination causes slapd to utilize 100% cpu time when issueing searches against parts of the DIT containing attribute-value pairs "created" by dynlist:

overlay dynlist dynlist-attrset extensibleObject memberURL uniqueMember

overlay valsort valsort-attr uniqueMember dc=o2online,dc=de alpha-ascend

When run independent both overlays work flawlessly.

To be honest, I don't quite see the point in keeping sorted a set of values that by definition is dynamically built. There seems to be contradiction between the two overlays that prevents them from being used together anyway. If your intention is to partition a tree so that the intersection of data subjected to valsort and data subjected to dynlist is empty, then I guess the solution is to use the <attri> and <baseDN> parameters of valsort to exclude those entries that are subjected to dynlist. If this is not enough, you could ask for an enhancement that turns the <attr> <baseDN> into a more general specification that allows increased granularity; for example, an attr and a filter, which incidentally could be specified by means of an URL so that base, attribute list, scope and filter can be present.
