log of Portage hang with postfix (portage_hang.log.bz2,106.75 KB, text/bzip2)

Description Robert Hillyerd 2003-08-06 06:37:32 UTC
The bug has been around for multiple versions of portage
Attempted deleting distfiles, ebuilds and digest files, problem still remains
after rebuilding digest files.

I have been unable to upgrade postfix since 2.0.3, here is what it echoes out
>>> emerge (1 of 1) net-mail/postfix-2.0.13-r1 to /
>>> md5 src_uri ;-) postfix-2.0.13.tar.gz
>>> md5 src_uri ;-) pfixtls-0.8.15-2.0.13-0.9.7b.tar.gz
At hang usermod takes up all remaining cpu time and does nothing.

I don't think it can really be replicated
emerge =net-mail/postfix-2.0.9
watch it hang

you may contact me at but if it returns mail,
that's cause postfix isn't working ;)
so email me at if that happens
if you are a dev, contact me and I'll give you any specific information on this
machine/config to help you get this weird fluke bug resolved.

could you provide the results of `cat /proc/cpuinfo` and also `emerge info` ?

Comment 3 Markus Nigbur (RETIRED) gentoo-dev 2003-08-07 03:46:52 UTC
My guess is, that your system is kinda slow, maybe related to cpu, or harddisk (hdparm running)?
because the next step will be unpacking the sources. It even takes some seconds on my PIV 1800 with ATA100 disks.

so could you try if it just continues after some more time?
Comment 4 Robert Hillyerd 2003-08-07 07:08:17 UTC
I've given it that chance, I've let it sit there for a good 5 minutes and it hasn't progressed beyond the hang point. This is the only package that I'm aware of that it's been doing this to. and has been happening since 2.0.3 of postfix. Files Significantly larger tend to get through this point within 5-10 seconds
I do run hdparm on my drive. I assure you this isn't HDD/CPU related.
Comment 5 aethyr 2003-08-12 13:38:21 UTC
Wait, why are you deleting digest files?

I'd delete the relevant distfiles, then emerge sync.

If you want a really clean start, then `rm -rf /usr/portage/net-mail/postfix && emerge sync` and try again.
Comment 6 aethyr 2003-08-12 13:44:49 UTC
and for the heck if it try:

`emerge /usr/portage/net-mail/postfix/postfix-2.0.13-r1.ebuild`

instead of

`emerge postfix`
Comment 7 Robert Hillyerd 2003-08-14 17:09:44 UTC
After deleting /usr/portage/net-mail/postfix dir
and emerge syncing......

>>> emerge (1 of 1) net-mail/postfix-2.0.13-r1 to /
>>> md5 src_uri ;-) postfix-2.0.13.tar.gz
>>> md5 src_uri ;-) pfixtls-0.8.15-2.0.13-0.9.7b.tar.gz
5 minutes were given..... *hang*
Comment 8 Nicholas Jones (RETIRED) gentoo-dev 2003-08-15 16:07:16 UTC

strace -f -o portage_hang.log emerge postfix
and post that here for me please. Stop it in
reasonable amount of time.

bzip2 it please.

bzip2ed for your convenience
Comment 10 Robert Hillyerd 2003-08-16 14:52:34 UTC
there's the log, it's just screaming infinant loop.
bugzilla gave me an error when uploading which i submitted to the webmaster
if for some reason, the file isn't there
you can get it here
Comment 11 Nicholas Jones (RETIRED) gentoo-dev 2003-08-16 18:16:54 UTC
What's in your syslog, and does the following work?
# usermod -G mail postfix

Relevant chunk from strace:

16213 execve("/usr/sbin/usermod", ["usermod", "-G", "mail", "postfix"], [/* 177 
vars */] <unfinished ...>                                                       
16213 connect(6, {sa_family=AF_UNIX, path="/dev/log"}, 16) = 0                  
16213 send(6, "<86>Aug 16 17:24:07 usermod[1621"..., 65, 0) = 65                
16213 rt_sigaction(SIGPIPE, {SIG_IGN}, NULL, 8) = 0                             

Comment 12 Robert Hillyerd 2003-08-16 19:16:57 UTC
Aug 16 22:12:53 [usermod] add `postfix' to group `mail'
---- when doing----
usermod -G mail postfix
in /etc/group ---- mail::12:mail
so no addition there.
Comment 13 Martin Holzer (RETIRED) gentoo-dev 2003-11-17 04:34:01 UTC
is this still an issue ?
Comment 14 Ajay Sharma 2004-06-22 20:40:35 UTC
ping... is there still a problem here?  Nothing relevant has been posted after August 2003.
