The manufacturing process is likely making more than the storage can hold. Try lowering the number of workshops.
This is like duplicate of a number of bug reports related to manufacturing processes.
First being output amount calculation is wrong: Production bonuses apply twice per shop (Exponential bonuses)
Second being about buildings with too small storage will report as "full inventory": Processes don't output if a single run exceeds storage (merged with this though)
