FE6 Buildsys Lockups

[Warren Togami]

During the past 2-3 weeks or so, gcc and sed have been deadlocking 
during FE6 builds in our plague+mock based Extras buildsys.  This has 
been happening consistently when building certain packages, and always 
the i386 arch deadlocking.  Our attempts of getting any useful info from 
strace or gdb have failed.

Our x86_64 Extras buildsys hosts appear to be FC3 with 
kernel-2.6.12-1.1376_FC3smp.  Meanwhile we haven't seem to run into 
similar deadlock problems of our FC6 mock builds inside of Red Hat, 
where the host is RHEL4 U3.  Several of us suspect some kind of kernel 
problem on the buildhosts.

Here are the next steps that I am trying:

1) Testing those builds on our existing FC3 buildhosts, but with RHEL4 
kernels.
2) Testing those builds on Red Hat's internal buildsys, which is also 
mock based but with RHEL4 hosts.

I am proceeding to install RHEL4 kernels and rebooting the Extras build 
hosts now.
