I've had a few Rails processes raise (Errno::ESPIPE) "Illegal seek" on
a file upload action, and when they do, they start eating up 100% cpu
and stop responding. Sometimes they're still in the passenger-status
list, sometimes not.
I'm using Passenger 2.0.2 with Rails 2.1.0
I received this backtrace from the Rails exception notifier plugin. It
looks like the exception is when flushing the response to the client.
Does anybody know why it might be happening?

Which version of Ruby are you using? And are you capable of reliably reproducing this problem?

I'm using Ruby 1.8.5 from the yum package for CentOS. So far I haven't
been able to reproduce the problem, but it happens a couple times a
day if you have a suggestion for something to try.
$ ruby -v
ruby 1.8.5 (2006-08-25) [x86_64-linux]
$ uname -r
2.6.18-92.1.6.el5
$ yum list | grep ruby.x86_64
ruby.x86_64 1.8.5-5.el5_2.3
installed

You might want to give Ruby 1.8.6-p286 a try. The problem that you're experiencing might be a Ruby bug.

This is actually a serious problem. After a while our upload servers
have at least 4 processes that hang in this state and chew up the
CPUs. Has anyone else seen this? Here is the repeated output of
