Are you using NIC teaming? According to Veritas, Compaq NIC teaming is 
notorious for not playing nice with NBU, and will cause 41 errors. IIRC, 
they recommended grabbing the drivers directly from Intel, rather than 
using Compaq's driver.

NAV can also cause this problem, if it's scanning while taking full 
backups (in my case). Don't ask me why "full" vs. incremental, but I had 
this problem each time I took a full backup on a ~200G partition. Once I 
moved the full backup two days later than it was originally scheduled, 
the 41 errors disappeared.

HTH,
Steve
