Description Matt Warnock 2004-12-15 09:49:07 UTC

Running a recent (few days old) GRP Gentoo 2004.3 system, on a 630Mhz AMD Duron with 1GB memory, 2GB swap, 60 GB drive.  I did an emerge world when done, which installed Samba 3.0.8, which segfaults before it initializes.  Thought I'd try 3.0.9, so I unmasked it, then emerged samba.  I have not altered USE flags.

emerge spawns an ebuild.sh, which spawns another ebuild.sh, which slowly grows to consume all memory (I'm not too sure how a shell script manages this, is there some seriously recursive function there).  

Reproducible: Always
Steps to Reproduce:
1. unmask samba so 3.0.9 is the currently selected build
2. emerge samba
3. switch to another console and run "top".  Watch the system slow to a crawl!

Actual Results:  
Samba took more than 8 hours just to download the files (then I killed it and 
tried again, with the same result).  It never got to the actual compiling.  

Expected Results:  
Compiled samba. ;-}

I am a Gentoo newbie, but on Linux (mostly RedHat) since '93 or so. Please 
feel free to email any questions, since there may be things I am missing as a 
Gentoo newbie.

Here is a "ps aux" taken while the ebuild is running:

Strange: you have stable packages only, so I think that's not related to samba, but portage (which is very strange anyway).
Can you re-'emerge sync && emerge portage; emerge baselayout' and then 'emerge samba'?

closing: this was due to ext2 fs corruption in which portage tree resided.
