SU and RPM problems.

Hello, my SU and RPM commands tend to get stuck pretty often. I am using Redhat 8.0 with Directadmin.

for su, when I su into someother user, at times, it will get stuck, and I will have to open up another SSH connection, find out the pid of a process call "stty erase ?" and kill it to unstuck myself.

for rpm, when it gets stuck, I will have to kill the process, rebuild the rpm index, and run it again.

now I am wondering if I broke something somewhere on my box, or is this some common bugs that I am not quite aware of, and if there is any way to fix this? can anyone please shed some light please?

Thank you very much.
