>Environment:
System: NetBSD thirdstage.duskware.de 6.99.11 NetBSD 6.99.11 (MODULAR) #9: Thu Sep 20 11:12:29 CEST 2012 martin@night-porter.duskware.de:/usr/src/sys/arch/sparc64/compile/MODULAR sparc64
Architecture: sparc64
Machine: sparc64
>Description:
Running the /usr/tests/lib/libc/sys t_pipe2 test sometimes ends with
a non-exiting zombie process:
12310 ? Z 0:00.00 (t_pipe2)
This is a new effect, but not always reliably reproducable - race condition
in recent lwp exit changes?
>How-To-Repeat:
cd /usr/tests/lib/libc/sys && atf-run t_pipe2 | atf-report
and watch it hanging sometimes.
>Fix:
no idea

I made a number of related commits in this area last month to resolve
"the zombie that wouldn't die" problem that I had been seeing. I can
no longer reproduce my problem.
Can you please check to see if your issue is also fixed? It sounds like
pretty much the same issue...
Thanks!
