Why does DBCC SHRINKFILE work inconsistently in a database job?

'Cannot shrink log file 2 (Claim_Log) because all logical log files are in use.'

DBCC SHRINKFILE (N'Claim_log' , 0, TRUNCATEONLY)

'Executed as user: *. Cannot shrink log file 2 (Claim_Log) because all logical
log files are in use. [SQLSTATE 01000] (Message 9008)  DBCC execution completed.
If DBCC printed error messages, contact your system administrator. [SQLSTATE 01000]
(Message 2528).  The step succeeded.'
