williamcs The following are the answers to your questions.
1. Based on F5 documentation the value can be within range 1 and 2,147,483,647.
2. The only real downside I see to increasing the timeout value higher than the default is if you have a high connection virtual server you could theoretically reach a very large persistence table which would cause performance degredation.

MVPwilliamcs Sadly I am not able to find the documentation that I am referencing because it was some obscure page. I logged into one of my F5 devices and it seems as though the timeout can be a specified large range or you can change "specify" to "Indefinite" which means the persistence entry would last forever if you picked the "Indefinite" option. I would say setting this value would also have the same result as my answer for question number 2 above but to a much greater extreme. I do not see any instance other than for testing purposes where you should ever set your persistence timeout to "Indefinite" because of this.
