[gentoo-user] troubles with emerge --sync

[Alexander Clark]

I'm getting a strange error on one particular box when I try to emerge  
--sync:

rsync error: sibling process crashed (code 15) at main.c(1505)  
[generator=3.0.6]
>>> Retrying...
dmesg told me:

grsec: From 66.55.54.28: signal 4 sent to /usr/bin/rsync[rsync:30041]  
uid/euid:0/0 gid/egid:0/0, parent /usr/bin/rsync[rsync:30040] uid/euid: 
0/0 gid/egid:0/0

I had done an emerge -uDN world, so it's quite possible that rsync got  
recompiled in a screwy way. I've tried re-emerging it since then, but  
without changing whatever went wrong, that didn't prove anything.

Can anyone suggest a next step for probing deeper into what happened,  
or finding a fix?
