New install of Passenger (replacing mongrel_cluster) segfaults apache

[Matt R]

Trying to replace mongrel_cluster with passenger. Installed via the
gem and ran the install "OK". Added the correct entries to my
httpd.conf and vhosts.

Restarting apache results in every child process failing:
[Tue Jan 13 16:37:42 2009] [notice] SIGHUP received. Attempting to
restart

[Tue Jan 13 16:37:51 2009] [notice] child pid 6679 exit signal
Segmentation fault (11)


Running the spawner from the command line gives:
passenger-spawn-server
*** Exception Errno::EBADF in spawn manager (Bad file descriptor)
(process 16929):
from /usr/local/lib/ruby/gems/1.8/gems/passenger-2.0.6/bin/passenger-

which is
input = IO.new(DEFAULT_INPUT_FD)

It fails with both regular ruby and ruby ee.

The rails production log shows requests making it just fine (e.g. it
is processing). Any ideas?

Thanks!!!!

$ cat /proc/sys/fs/epoll/max_user_instances
128

+This is the maximum number of epoll file descriptors that a single
user can
+have open at a given time. The default value is 128, and should be
enough
+for normal users.

The problem is that 128 is too low for your configuration.
$ echo 1024 > /proc/sys/fs/epoll/max_user_instances

will solve your problem ;)

That didn't fix the problem, but updating to 2.1.2 seemed to work!
