Win7 hosts with centOS causing VERR_UNRESOLVED_ERROR

[laurnet]

Hello,

I am running into issues with my centOS Virtual Machine running on Windows 7 where it will crash at (seemingly) random times.

Yesterday I ran into another issue forcing me to defragment the disk the Images are stored on (identical issue as in virtualbox. org/ticket/11030)

I have however been getting the following error over the past week, which pauses the VirtualMachine, and won't let me resume it either (the error will re-appear).

00:01:06.899026 )AioMgr0-N: Request 0x00000008972e70 failed with rc=VERR_UNRESOLVED_ERROR, migrating endpoint D:\Web\B - Virtual Server Images\CURRENT\VI-3028-FTL Clone\Snapshots/{aa6142fd-9ae5-44ca-8203-320cd66ad94a}.vmdk to failsafe manager.

Does anybody have an idea of where this might be coming from?

Thanks
