Bug#851241: www.debian.org: packages.debian.org update hangs every now and then

Package: www.debian.org
Severity: normal

     Hi,

 I got notified today that the packages website didn't update, and that
this seems to be an issue appearing more regularly.  I didn't had much
time unfortunately to investigate it further, but this is what appeared
to me:

#v+
pkg_user 21873  0.0  0.0 103296  5192 ?        S    Jän07   0:07 sshd: pkg_user@notty
pkg_user 21887  0.0  0.0   4336   764 ?        Ss   Jän07   0:00  \_ dash -c /srv/packages.debian.org/bin/push_update

pkg_user 21958  0.0  0.0   4224  1476 ?        S    Jän07   0:00          \_ run-parts --verbose /srv/packages.debian.org/cron.d

pkg_user 20378  0.0  0.0   4336   712 ?        S    Jän07   0:00                      \_ sh -c sort  -T /srv/packages.debian.org/tm
pkg_user 20379  0.0  0.0   9080  3864 ?        S    Jän07   3:24                          \_ sort -T /srv/packages.debian.org/tmp -
#v-

 The running time of parse-contents was increasing, but the sort didn't
do anything. An strace showed that it was hanging:

#v+
$ strace -p 20379
Process 20379 attached
write(1, "-data:kfreebsd-i386\nyp.margorp_e"..., 4096^CProcess 20379 detached
 <detached ...>
#v-

 Unfortunately I didn't had the time to investigate further, but if it
hangs again and maybe at the same place I guess the tmp file(s) would be
useful to investigate further.

 Sorry for not much more right now,
Rhonda
