Could you show 'dmesg | tail -n 20' and 'strace -p pid' for saw what take place when portage freezes ?

unfortunately, I have been rebooted system because emerge was eating my CPU. This issue appears sometimes. I hope, it appears in the near future. 

[Comment 3 Zac Medico 2009-04-20 18:21:49 UTC]

Next time that it happens, trigger the python debugger by sending the emerge process a SIGUSR1 singal:

  killall -s SIGUSR1 emerge

At the debugger prompt, type these two lines to get a backtrace:

  s
  bt

The 's' command is necessary in order to step out of the signal handler, and 'bt' displays the backtrace. Please post the backtrace.

[Comment 4 Till Korten 2009-12-14 06:52:28 UTC]

I'll do that as soon as the problem appears next. However as described that might take a week or so...

[Comment 5 Till Korten 2009-12-14 07:54:36 UTC]

Interestingly, after I delete, the manifest, the digest works. The Manifest hasn't changed, though. I also tried to change the timestamp of the Manifest to an older time using touch but that did not have an effect, either.

Could it be that portage caches the ebuilds somewhere and the problem is in the cached ebuild?

[Comment 6 Till Korten 2009-12-14 08:00:28 UTC]

please ignore my last two posts, I posted them in the wrong bug. Sorry!!!

Some time has passed. Please comment on this bug and reopen it if it happens again; when you do so, can you provide the instructions from Comment #3? If you can't reopen, as you are perhaps a new user; feel free to start a new bug.
