VNCTransport error message unclear

Hello!

I have a interesting message in AS on Windows 2003 SP2 do discuss. The mirror network is based on Gigabit NICs, the drive runs on HP Raid controllers. The situation is as follows:

In the event log, I see the esg119424 related Warnings:

Legato link connection failed, event ID 3372,

Write I/O error, event ID  3357

but not the one that the datasource member is broken.

Instead I see the message:

VNCTransport: Mapping from physical page to system space fails in VncTransportPut, event ID 4333.

I wonder if this is a risk situation that the physical page mapping on the disk is not working and I should consider rebuild the drive file system or if it is only a problem related to the physical mirroring network / drivers operating on the mirroring line?

Any comments appreciated!
