Subject: [9fans] how to hang rio
Topicbox-Message-UUID: 022e155c-ead3-11e9-9d60-3106f5b1d025

I'm seeing an interesting hang scenario on rio, and I can't remember
if I posted it to this list.

The scenario is simple. I drawterm in to a qemu or lguest plan 9 guest.

make a window.

cpu -h somehost.
It hangs for whatever reason. tcpdump shows it hanging on 17010 -- cpu
sending to 17010, remote host not responding.

Do any rio operation. It doesn't matter what -- middle, right are
best. Just one op. make a window, whatever. It's the last op you will
do with rio for that session of drawterm.

I can drawterm in again and get another session. It's fine. I can kill
the hanging cpu from that session. At that point, the hung rio
unhangs.

Interesting, eh?
