Not a BUF latch. Error Re-Indexing

We have a SQL Server 2000 Enterprise Edition database on a Windows 2000
Advanced Server.
Weekly we have a job that drops all indexes on the database and recreates
them.
This job runs at the same time the daily backup and transaction log execute.
We received following error caused by the re-index:
"Time out occurred while waiting for buffer latch type 4..."
Please help me resolve these latch errors.
Thanks,

and recreating all indexes (I hope you use DBCC DBREINDEX btw) at the same
time as a backup. In general running the operations in parallel will not be
much quicker than running them in series (because your resources, specially
disk I/O, are limited). And if your backup finishes before the reindexing
finishes, part of your indexes will be reindexed and part not, but you don't
know exactly which.
