I can verify that the file system is not set to read-only and that there are not multiple MarkLogic processes. I will file a support ticket, but are there any other suggestions as to where to look in the meantime?

Most SVC error codes are fairly severe. My own first thought is that "The process cannot access the file because it is being used by another process" means that there are two different MarkLogic process trying to use the same forests. I would check that possibility first. Keep in mind that there are normally two processes: the worker process and the watchdog process. But if you see three or more, that's definitely a problem. -- Mike On 16 Oct 2012, at 11:47 , Nelson Wells <nelson.we...@icainformatics.com> wrote: > Hi all, > > I'm having an issue with a MarkLogic instance that hosts several app servers > and databases.
