Set seed affects rstan process?

Hi, I am working on rstan now. I found when I change the seed number, my process will differ.
For example,( I have 4 chains)
I use seed(1234), only chain 2 works.
seed 1111, all chain work but not converge
seed 1,chain 2,3,4 work
seed 2, no chain works
seed 11, chain 3 works

Is it reasonable?

There are some threads in here where folks recommended not setting the seed. I will dig around and see if I can find those. I think it had to do with behavior like this?
