I have 64bit OES 2 Linux on powerful server, there are almost no users connected just to this server, but recently, ndsd process takes up to 300% cpu. This high load starts about a minute after ndsd start.

Server is almost completely updated (updated like a month ago)

ndstrace didn't show any synchronization when this load is performing, also eDirectory is healthy and there aren't such problems on other servers in tree.
Do you have a clue?
