Hi,

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.
