Subject: [9fans] drawterm hangups
Date: Tue, 18 Aug 2009 13:03:55 +0100	[thread overview]
Message-ID: <df49a7370908180503s13e01149kbc5dd42d61d9ada8@mail.gmail.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 912 bytes --]

every so often using drawterm (mac os version) i've been getting
a hangup. it's not a sudden thing - rio continues running,
but first i lose keyboard input, then mouse input.

it seems to be to do with one window, which was probably in
rawon mode.

if i get access to the rio session via another route,
then i find that it's still working ok, except
that a write to the offending window's cons file
will hang (it's interruptable) - other windows' cons files
are writable, and all the text files are readable too.

i've spent an hour or so on this but can't afford any more
time, so if anyone has any ideas, please let me know.
i'll leave the offending drawterm running just in case.

i attach two files, showing the process listing and stack
traces of all the rio processes. before.txt is after the keyboard
hangup but before the mouse hangup; after.txt is after the mouse
hangup.

  rog.
