NetBackup catalog backup error

Hey everyone,

I am getting a NetBackup catalog error and I am hoping someone can you me understand why i keep getting this error.  

Error bpbrm(pid=4184) from client veritasarsenal: ERR - failure reading file: E:\Netbackup\NetBackup\db\error\errordb.lock (WIN32 33: The process cannot access the file because another process has locked a portion of the file. )

I am running version 7.1.0.4 and Windows server 2003 R2. Master server name: veritasarsenal.
