Limit has been reached for the logical resource

Hi,

We are using symantic veritas 6.5.6 to backup all unix and windows servers.Our backup server is on win2k8 enterprise 64 bit.

We recently come across issue where backup of some policies.

I have enabled multiplexing on both policies and storage unit.

I have 4-5 policies configured on same pool.Everytime those policies run they run sequentially not parrallelly.

I have checked multiplexing on both ppolicy and storage units and they are enabled.

Please find logs below:
