I have ran into this before, but it's been a while.  At the time I would just delete the client then re-add just to get it done and move onto something else.

I have a client that has been backing up without issues until this morning.  The VMware client is sitting in queue at waiting-client status.  All other vm's backed up without issue when the scheduled jobs ran along with this one client.  I have kicked off a backup of a client while this one is still waiting, the client I kicked off backed up with issue.

Since the job is waiting, there isn't any log to look at and I don't think there is a log anywhere, node or proxy, at this point - unless I am wrong?

Anyone have any ideas?

I know I can delete the client then re-add it, but then I have to stop my replications running and what not.  But I would rather fix the problem, if there is anything that could be fixed, instead of just deleting re-adding.
