In 1.1.89 and 1.1.90 I've been seeing a problem that may have
something to do with the tty code or with Linux AFS. This problem
doesn't seem to exist in Linux 1.1.68 at least. When no one is logged
in at the console and a user logs in from outside of MIT with
non-kerberized telnet and logs in with the athenaized login and an
Athena homedir, occasionally the user will get a prompt and then on
pressing return will get logged out and the tcsh process
(/afs/sipb/project/tcsh/tcsh) will go into diskwait:
jhyun 634 0.0 0.2 555 36 con D 08:43 0:00 -tcsh
netstat -a doesn't list the connection anymore and the login process
has gone away. This problem never seems to happen
when someone is logged into the console (and/or is running X)
so is always low memory conditions and is usually
sometime in early morning ~8am when net traffic should be low.
Any ideas? This has happened at least 5 times and most of the time
nothing gets syslogged.
