We are not having any problems so far. Our question is regarding the delay in executing the "reverse" and the error below:

26/05/2012 2:21:18: ADMIN: 6: Indication: NULL list in addToSendList
26/05/2012 2:22:36: ADMIN: 6: last message repeated 15 times
26/05/2012 02:22:36: CFS: 6: / fs-nfscas01: path is unavailable (frozen) or invalid.
26/05/2012 02:23:58: CFS: 6: last message repeated 5 times

Why did these alert was triggered and what's themeaning of this?
