Determine if pine itself is hanging by running it in screen on the
remote host. Determine if you have connection problems by making the
ssh client verbose, ssh -vvv. If your environment requires you to proxy
ssh through a bastion to get to hosts in the wild, know the bastion's
keepalive/timeout configs.
I added a /etc/sysctl.d/10-openupssh.conf file that contains the
following:
net.ipv4.tcp_sack = 0
which may help. Without it, certain SSH things like scp and sftp would
slow to a crawl after a while. This may be what you're seeing.
