Description Dan Horák 2010-09-03 12:12:43 UTC

I can't build glibc-2.12.90-8 for s390x and s390 because the build logs get filled with repeated "in signal handler/on alternate stack" messages and this continues for hundreds of MB (I got even a 2GB+ log), normal build log is about 400 KB so I cancel the build. Please see the URLs for more details.

wrong/canceled build:
http://s390.koji.fedoraproject.org/koji/taskinfo?taskID=203936

I was able to do a successful build of 2.12.90-7 a month ago and its results are at http://s390.koji.fedoraproject.org/koji/buildinfo?buildID=34963
If I can trust IRC logs then it was with kernel -44.1.el6 on the builders and cpuplugd disabled.

I've tried multiple kernels
kernel-2.6.32-44.1.el6.s390x
kernel-2.6.32-71.el6.s390x

and also tried disabling the cpuplugd daemon (enabled by default) that turns cpus online/offline depending on the load.


interesting parts of the logs:

Comment 1 Andreas Schwab 2010-09-07 10:13:49 UTC

I cannot reproduce that on RHEL5.

Comment 2 Dan Horák 2010-09-07 12:01:54 UTC

This issue first occurred when we switched the builders to RHEL6 Beta2. Let me know (I'm "dhorak" on internal IRC) if you would need access to one of the Fedora builders.

Comment 3 Dan Horák 2010-09-13 19:05:53 UTC

build of glibc-2.12.90-10 failed with the same problem, this time only on s390 and s390x was OK, see http://s390.koji.fedoraproject.org/koji/taskinfo?taskID=205809 for details

Comment 4 Andreas Schwab 2010-09-14 13:23:08 UTC

I'm unable to reproduce that on RHEL6 either.

Comment 5 Dan Horák 2010-09-14 15:44:34 UTC

Seems it's not 100% reproducible. I did 2 builds (s390x) today in the Fedora 14 chroot running on top of RHEL6 and the first run successful, but in the second one I got the endless loop.
