FE6 Buildsys Lockups


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.
