DirXML Log Event -------------------
Driver: \ARZ-TREE\arz\ress\driverset12\ADM075
Channel: Publisher
Status: Error
Message: Code(-9010) An exception occurred: novell.jclient.JCException: initVlistIterator -6038 UNKNOWN ERROR
----------------------------------------------------------------
when i fire up imonitor and navigate to that server (via another one) - error -6038 is displayed. sc stop "nds server0" helps to get the error -6038 away. some time after the restart errors on some replicas this server is holding (as master) are shown (delta sync is marked as red) but soon go away as well.

two of my productive servers had that problem yesterday, a third and one the yesterday´s servers have it today.

thanks in advance on ideas how to better that :)
