Server crash - Bad VBlock Handle (3\7)

Hi,Yesterday our server crashed with the error - Stack base=0x0012F42C stack size = 20948 bytes PANIC OSVBlockAddr: Bad VBlock handle (3\7)

I’ve done a search and it according to various posts, this is a bug fixed in 6.0.2 CF1 however we’re already running this.

The logs show that the server was routing mail at the time and had just finished updating various mail files.

Has a corupt mail message caused this ?

Thanks.
