Originally you said:

Multiple preprocessers will run and preprocess different log files moving the results to a hash then a single processer will pull contents from the hash and delete the element after processing.

So, the preprocessors read files and write to a shared hash; and the processor reads the hash. Which somewhat agreed with this description.

But now you say:

Each preprocesser will access a shared hash to access the logs.

The preprocessors read the hash to access the logs.

At this point, I've no idea what it is that you are doing, so the best I can say is good luck.
