[mirror-admin] Heads up if your running Fedora w/ a 2.6.27 kernel

[J.H.]

Just a quick heads up to any mirror that is running a 2.6.27 kernel.  If 
you are seeing segfaults in Apache like the following:

[Tue Jan 27 04:45:21 2009] [notice] child pid 5322 exit signal 
Segmentation fault (11)
[Tue Jan 27 04:45:23 2009] [notice] child pid 5496 exit signal 
Segmentation fault (11)
[Tue Jan 27 04:45:30 2009] [notice] child pid 5323 exit signal 
Segmentation fault (11)
[Tue Jan 27 04:45:32 2009] [notice] child pid 5327 exit signal 
Segmentation fault (11)
[Tue Jan 27 04:45:34 2009] [notice] child pid 5330 exit signal 
Segmentation fault (11)
[Tue Jan 27 04:45:36 2009] [notice] child pid 5332 exit signal 
Segmentation fault (11)
[Tue Jan 27 04:45:38 2009] [notice] child pid 5861 exit signal 
Segmentation fault (11)

and can't explain what's going on, there was a recent kernel change that 
effects epoll (which Apache switched to a while back) and causes you, by 
default, to only have 129 children running before Apache's children 
would segfault.

Just thought I'd share since I can't be the only one who has hit this in 
the last couple of weeks.
