I have stumbled across a bug that's driving me bonkers. Here's
the setup:
- Log in to a 4.2-RELEASE box.
- Run mutt (1.2.5i, built from ports)
- Get dropped into an editor (new message, reply, it doesn't matter)
- Enter insert mode in vi
- Paste in > 1k (approximately) of text
Bam, frozen window. It won't respond to anything. Here's output
of top for that string of processes:
PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU CPU COMMAND
75136 bicknell 18 0 1348K 924K pause 1 0:00 0.00% 0.00% tcsh
84462 bicknell 10 0 2736K 1904K wait 0 0:00 0.00% 0.00% mutt
84475 bicknell 10 0 620K 232K wait 1 0:00 0.00% 0.00% sh
84476 bicknell 4 0 1900K 1664K ttywri 0 0:00 0.00% 0.00% vi
(tcsh -> mutt -> sh -c vi -> vi)
Vi always ends up stuck in ttywrite, and yes, I can easily reproduce
this over and over.
>From another window, try to kill the processes as a user, no effect
with -9 or regular. Try to kill them as root, no effect normal. Kill
them -9 as root, and all but the first shell will go away, here's
ps output from an earlier occurance:
PID TT STAT TIME COMMAND
20986 p0- IEs+ 0:00.08 -tcsh (tcsh)
And top of the same:
PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU CPU COMMAND
20986 bicknell 4 0 1344K 908K ttywai 1 0:00 0.00% 0.00% tcsh
If I run vi on its own (or cat -, or emacs, etc) I can't make this
happen. I can't make it happen with another editor under mutt (eg
emacs). But let mutt start vi and paste a reasonable size junk
and bam, its frozen. I've also tried it from different terminal
emulators, over both ssh and telnet, same results.
I'm at a loss as to what might be happening, or what to do next to
debug this particular problem. Anyone have a suggestion?
