pexpect module pegging cpu ram to 100%

[Kathy L]

We are using the pexpect module when running asynchronously and telling it to open /bin/bash.  (This is all trying to get master sockets working). When we do this from a Debian 10 or Debian 11 hosts operating against another Debian 10 or Debian11 host it pegs the cpu to 100% and hangs. We've tried this on Ansible 7.7, 8.1 and 8.4 and they all behave the same way. Has anyone used this before in this manner?
