Package: lintian
Version: 2.5.74
Severity: important

Seen twice on lindsay.d.o in the last 24 hours.  The exact reason is
unknown, but it is probably during the unpacker (last non-error in the
log is lintian starting the unpack, plus previously we had a race-condition
in the unpacker that could trigger a similar fork-bomp situation).

Most likely we never fixed this condition and only made it
"sufficiently unlikely" until gcc-8-cross-ports showed up.


For now, I have disabled the crontab on lindsay.d.o to avoid it taking
down our host.

Thanks,
~Niels

Hi,

Recent versions of Lintian complete peacefully for gcc-9-cross-ports
and gcc-10-cross-ports. There are no fork bombs or other issues. Log
files for both are attached.

The runs merely take time, presumably because the packages are large
and complex. They also require plenty of space in /tmp (approximately
50 GB for gcc-10-cross-ports running locally).

$ ls -al /mirror/debian/pool/main/g/gcc-10-cross-ports/ | grep -v ^d | wc -l
557
$ du -sh /mirror/debian/pool/main/g/gcc-10-cross-ports/
8.6G    /mirror/debian/pool/main/g/gcc-10-cross-ports/

$ ls -al /mirror/debian/pool/main/g/gcc-9-cross-ports/ | grep -v ^d | wc -l
495
$ du -sh /mirror/debian/pool/main/g/gcc-9-cross-ports/
2.0G    /mirror/debian/pool/main/g/gcc-9-cross-ports/

The exam subject from the original filing, gcc-8-cross-ports, was no
longer available in unstable. An effort was made to obtain the sources
and installation packages for all supported architectures. It likewise
completed peacefully. That log is also attached.

$ ls -al ../bugs/gcc-8-cross-ports/ | grep -v ^d | wc -l
569
$ du -sh ../bugs/gcc-8-cross-ports/
1.9G    ../bugs/gcc-8-cross-ports/

Not sure if Olly's problem with wxwidgets3.0 was related, but it ran
fine. That log is attached as well.

The reported issue is no longer present. Closing this bug.

Kind regards
Felix Lechner
