Relog dropping samples

From two Windows 2003 R2 servers, I have logs saved with the following

counters:

Processor/%Processor Time

Physical Disk/Average Disk Queue Length

Physical Disk/Avg Disk Read Queue Length

Physical Disk/Avg Disk Write Queue Length

Physical Disk/Disk Read Bytes/sec

Physical Disk/Disk Write Bytes/sec

SQL Server/Transactions Per Second

If I attempt to convert the log files to csv format, it returns zero

samples.

SERVER 1:

C:\relog LoadTest_10-06-08_ETS_000002.blg -f csv -o ets.csv

Input

----------------

File(s):

LoadTest_10-06-08_ETS_000002.blg (Binary)

Begin: 10/7/2008 10:50:24

End: 10/7/2008 16:32:26

Samples: 2053

Output

----------------

File: ets.csv

Begin: 10/7/2008 10:50:24

End: 10/7/2008 16:32:26

Samples: 0

The command completed successfully.

SERVER 2:

relog LoadTest_10-06-08_gns_000002.blg -f csv -o gns.cs

Input

----------------

File(s):

LoadTest_10-06-08_GNS_000002.blg (Binary)

Begin: 10/7/2008 10:48:17

End: 10/7/2008 16:29:37

Samples: 2049

Output

----------------

File: gns.csv

Begin: 10/7/2008 10:48:17

End: 10/7/2008 16:29:37

Samples: 0

The command completed successfully.

Looking for suggestions on what may be happening. On two other

servers, I get the expected conversion.

Thanks!
