Annoying error message 800. How to resolve it?

[geewizard]

Error nbjm(pid=3640) NBU status: 800, EMM status: Maximum job count has been reached for the storage unit

Everything is working correctly, I just get these errors. What can I do to get rid of them?

NetBackup 7.0, two NetApp filers, one Overland 2000E library, Win7 server

Settings that could affect this sort of error

Max job per policy
Max job per client
Max job per storage unit
Max concurrent write drives setting in storage unit
Check MPX level is schedules if using MPX

Other ideas, recreate storage unit, with NO jobs running, run nbrbutil -resetall
