Connected to localhost (127.0.0.1). Escape character is '^]'. Red Hat Enterprise Linux WS release 3 (Taroon Update 2) Kernel 2.6.10-rc2 on an i686 Connection closed by foreign host. A bsearch placed the bug between 2.6.9-rc1-bk[78], another bsearch on the changesets showed the problem is caused by this patch: roland@redhat.com[torvalds]|ChangeSet|20040831173525|30767 [PATCH] waitid system call My guess is, something about the new wait4(2) wrapper is causing the telnet daemon to declare success before its child, /bin/login, exits.
