System:

Weblogic 10.3.0, Documentum Administrator 6.5 SP 1, Taskspace 6.5 SP 1, Content Server 6.5 SP 1

Answer:

Try to change DFC.data.dir property value in dfc.properties to unique folder, for example in DA change it dfc.data.dir=C:/Documentum/da and in Taskspace change it to dfc.data.dir=C:/Documentum/taskspace
