snapshot replication error

[jabroni]

hi there,

i'm running snapshot replication on sql 2000 (SP2).
the snapshot agent fails with the following message:

"The process could not bulk copy out of table '[dbo].[syncobj_0x4145433644344643]'."

"I/O error while writing BCP data-file
(Source: ODBC SQL Server Driver (ODBC); Error number: 0)"

i schedule the agent to run every hour. the thing is that it fails one hour and then it succeeds the next.
i use all the default settings.

please help
cheers
