Problem
Certain savesets are taking a very long time to be retrieved and recombined from storage to be indexed. The issue can also be seen when performing a restore of the problematic items through normal methods including EVSVR - dumpsaveset. Certain items may take several minutes or more to restore properly when the item contain large numbers of recipients.
Error
A dtrace of StorageCrawler attempting to restore one of these problematic items shows extreme delays before the items is actually restored.
