I don't *think* it's a pine/alpine issue itself. If I come in using
shellinabox and open pine using a browser terminal, it doesn't happen. If I use some other client, e.g. roundcube, it doesn't happen.
Sigh. I take that back. I just happened using shellinabox. I guess it just happens less often...

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. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@alldigital.com - - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - - - - I was married by a judge.
