6.4.1cs.1 Bug with DSp allocation!

[Kurtstudio]

I am running the latest version of Channel Strip 2 0.3f13 on OX 13.3.4 , 733 Quicksilver Pro-Tools TDM 6.4.1cs1 .. What is happening my DSP allocation is inconsistent. I am mixing a record that is very large, Mix 5 TDM . I am running lots of plug in's and up on closing ands re-opening a session all recall fine except Channel Strip. I get the warning insufficient recourses. I could change to RTAS plug ins but I would prefer to not change anything. If I close Pro-Tools throw away my DSP preferences only, reopen Pro-Tools the problem session is fixed and all Channel Strips channels are fine from the session that before had said insufficient recourses and work on. Then I open another song to mix , that I had previously worked on the same situation happens. I go through same work around and etc....
