Shriking Database Job Fails With Errors.

Hi all
I have a Job



Code Snippet
set nocount on
declare @My_Return int
declare @command1 varchar(1000)
set @command1 = 'use [?] DBCC SHRINKDATABASE ([?], 50)'
print @command1
exec @My_Return = master.dbo.sp_MSforeachdb
@command1 = @command1
print @My_Return





Some of Errors are comming like

Cannot shrink log file 2 (modellog) because requested size (1234KB) is larger than the start of the last logical log file. [SQLSTATE 01000]

Cannot shrink log file 2 (xxxxx_Log) because all logical log files are in use. [SQLSTATE 01000]

Msg 1205, Sev 13: Transaction (Process ID 33) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. [SQLSTATE 40001]


Any suggestion appreciated.
