netbackup 7.5.0.7 causing high cpu during sql backup

We have several 2003 and 2008 servers running netbackup 7.5.0.7 and when netbackup tries to backup SQL dbs it causes extreme CPU spikes. We had this same issue with 7.5.0.6 but were able to get an EBB (3342502) patch that fixed it in that version but having since updated, the issue has returned. Anyone else having issues with CPU spikes and are aware of a fix for it?

Thanks
