Compressed file -- this file expands to 239 MB (sic!)
The important part is that it's stopping while writing to
the console, ie:
21593 --- SIGTTOU (Stopped (tty output)) @ 0 (0) ---
I have no idea why this happens in RHEL 6.5 but not anywhere else.
reproduced, # rpmbuild --rebuild --target=x86_64 libguestfs-1.20.11-2.el6.src.rpm ( omit message ...)

LAYOUT=partitions ../../run --test guest-aux/make-fedora-img.pl (it hangs here) It blocks errata tps-srpmtest, please help to fix ASAP I believe this is a bug in coreutils 'timeout' utility, in fact one which is still present upstream. I will upload two attachments which demonstrate the bug: $ gcc -Wall test.c -o test $ ./test $ timeout 4h ./test $ ./run <-- this command hangs with ./test putting itself into STOPPED state The following patch to coreutils fixes the problem for me. --- coreutils-8.21/src/timeout.c.old 2013-10-31 19:44:01.719755435 +0000 +++ coreutils-8.21/src/timeout.c 2013-10-31 19:50:07.634292913 +0000 @@ -443,9 +443,11 @@ { /* child */ int exit_status; +#if 0 /* exec doesn't reset SIG_IGN -> SIG_DFL. */ signal (SIGTTIN, SIG_DFL); signal (SIGTTOU, SIG_DFL); +#endif execvp (argv[0], argv); /* FIXME: should we use "sh -c" ... here? */ Created attachment 818048 [details]

test.c
Just disabling the code path is probably not correct way ;) ... however, it should at least be investigated - I don't think that priority urgent is the right one, though - as this should be "workaroundable" somehow in the test itself. I see it tracked on upstream tracker already - http://debbugs.gnu.org/cgi/bugreport.cgi?bug=15779 ... thanks Richard! Workaround in libguestfs: commit 7113aee0b439b411602d8d7d4b03bf02bc91b800 I'm also seeing this on Fedora 19. timeout has the --foreground option on fedora 19 Hoping we've fixed it properly (in libguestfs) this time: https://github.com/libguestfs/libguestfs/commit/e3f72805d108c601280b889692c47d7d825e6079 Verified with libguestfs-1.20.11-3.el6, Build passed Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
